arm: clean up v7 and v8 linker scripts for bss_start/end

commit f84a7b8f54db ("ARM: Fix __bss_start and __bss_end in linker scripts")
were moving the bss_start/end on c generated variables that were
injected in their own sections. The reason was that we needed relative
relocations for position independent code and linker bugs back then
prevented us from doing so [0].
However, the linker documentation pages states that symbols that are
defined within a section definition will create a relocatable type with
the value being a fixed offset from the base of a section [1].
So let's start cleaning this up starting with the bss_start and bss_end
variables. Convert them into symbols within the .bss section definition.

rockchip: load env from boot MMC device
Currently, if the environment is stored on an MMC device, the device
number is hardcoded by CONFIG_SYS_MMC_ENV_DEV. This is problematic
because many boards can choose between booting from an SD card or a
removable eMMC. For example, the Rock64 defconfig sets
CONFIG_SYS_MMC_ENV_DEV=1, which corresponds to the SD card. If an eMMC
is used as the boot device and no SD card is installed, it is impossible
to save the environment.
To avoid this problem, we can choose the environment MMC device based on
the boot device. The theobroma-systems boards already contain code to do
this, so this commit simply moves it to the common Rockchip board file,
with some refactoring. I also removed another implementation of
mmc_get_env_dev() from tinker_rk3288 that performed MMC boot device
detection by reading a bootrom register.

use DM_USB_GADGET instead of a board_usb_init() function.

rockchip: Add common default bss and stack addresses
On Rockchip the typical aarch64 boot steps are as follows:
- BROM load TPL to SRAM
- TPL init full DRAM
- use stack in SRAM at TPL_STACK addr
- use malloc heap on stack, size is TPL_SYS_MALLOC_F_LEN
- TPL jump back to BROM
- BROM load SPL to beginning of DRAM
- SPL init storage devices
- use bss in DRAM at SPL_BSS_START_ADDR, size is SPL_BSS_MAX_SIZE
- use stack in DRAM at SPL_STACK addr (or CUSTOM_SYS_INIT_SP_ADDR)
- use malloc heap on stack, size is SPL_SYS_MALLOC_F_LEN
- SPL load FIT images from storage to DRAM
- use stack in DRAM at SPL_STACK_R_ADDR
- use new malloc heap on stack, size is SPL_STACK_R_MALLOC_SIMPLE_LEN
- SPL jump to TF-A at 0x40000
- (optional) TF-A load OPTEE
- TF-A jump to U-Boot proper at TEXT_BASE
- U-Boot proper init pre-reloc devices
- use stack in DRAM at CUSTOM_SYS_INIT_SP_ADDR
- use malloc heap on stack, size is SYS_MALLOC_F_LEN
- U-Boot proper relocate to end of usable DRAM
- U-Boot proper init devices and complete boot
SPL have access to full DRAM, however, current configuration for text
base, stack addr and malloc heap size used at the different boot steps
are at risk of overlapping, e.g. when U-Boot proper + FDT grows close
to 1 MiB on RK3328/RK3399 or when pre-reloc and reloc stack and malloc
heap overlap on ROCK 5A.
Fix this by defining safe defaults for bss, stack and malloc size and
addresses. A range at around [60 MiB, 64 MiB) was chosen to be used for
bss and stack until U-Boot proper have been relocated to end of usable
DRAM. The range was primarily chosen to be able to accommodate SoCs with
a small amount of embedded DRAM, e.g. RK3308G has 64 MiB DRAM.
Overiew of the new common memory layout:
[ 0, 2M) - SPL / TF-A / reserved
[ 2M, +X) - U-Boot proper pre-reloc
[ -X, 64M) - bss, stack and malloc heap

[ -X, 63M) - SPL pre-reloc stack

rockchip: spl: Enable caches to speed up checksum validation
FIT checksum validation is very slow in SPL due to D-cache not being
enabled.
Enable caches in SPL on ARM64 SoCs to speed up FIT checksum validation,
from seconds to milliseconds.
This change enables caches in SPL on all Rockchip ARM64 boards, the
Kconfig options SPL_SYS_ICACHE_OFF and SPL_SYS_DCACHE_OFF can be used to
disable caches for a specific board or SoC if needed.

initcall: break loop immediately on failure
The current ordering always results in func pointing to the next
function in the init_sequence. e.g. if fdtdec_setup() fails, ret will
be set to the error code, then func will be updated to point to
initf_malloc(), only then is ret checked and the loop broken. The end
result of this is that the "initcall failed at ..." error will point you
to initf_malloc(), when the error actually occured in fdtdec_setup()!
This can be quite confusing and result in a lot of time wasted debugging
code that has nothing to do with the failure (ask me how I know :P).
Adjust the for loop to check ret immediately after the call and break
early so that func will correctly reference the failed function.

According to README CFG_SYS_BOOTMAPSZ section, in case both "bootm_low" and
"bootm_size" variables are defined, "bootm_mapsize" variable is not defined
and CFG_SYS_BOOTMAPSZ macro is not defined, all data for the Linux kernel
must be between "bootm_low" and "bootm_low" + "bootm_size".
Currently, for systems with DRAM between 0x4000_0000..0x7fff_ffff and with
e.g. bootm_low=0x60000000 and bootm_size=0x10000000, the code will attempt
to reserve memory from 0x4000_0000..0x4fff_ffff, which is incorrect. This
is because "bootm_low" is not taken into consideration correctly.
The last parameter of lmb_alloc_base() is the maximum physical address of
the to be reserved LMB area. Currently this is the start of DRAM bank that
is considered for LMB area reservation + min(DRAM bank size, bootm_size).
In case bootm_low is set to non-zero, this maximum physical address has to
be shifted upward, to min(DRAM bank start + size, bootm_low + bootm_size),
otherwise the reserved memory may be below bootm_low address.

the first bank, and reserves the rest of memory in the follow up banks.

general-purpose usage.
* One 3D GPU up to 50 GLFOPS
* H.264/H.265 Video Encode/Decode.
* Display support: 3x display support over OLDI/LVDS (1x OLDI-DL, 1x or
2x OLDI-SL), DSI, or DPI. Up to 3840x1080 @ 60fps resolution
* Integrated Giga-bit Ethernet switch supporting up to a total of two
external ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3xMMC and SD, GPMC for
NAND/FPGA connection, OSPI memory controller, 3xMcASP for audio,
1xCSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized Hardware Security Module with support for secure
boot, debug security and crypto acceleration and trusted execution
environment.
* One 32-bit DDR Subsystem that supports LPDDR4, DDR4 memory types.
* Multiple low power modes support, ex: Deep sleep, Standby, MCU-only,
