board: traverse: ten64: recognize board revision D
Ten64 board revision D is a variant that removes the USB hub
and PCIe expander/switch, but is otherwise compatible with the
main production "C" version.
At the same time, revise the printf specifiers (PCB version
"1064-0201%s") to reduce the number of string characters related
to the boot printout.

This patch adds general board files based on MT7988 SoCs.
MT7988 uses one mmc controller for booting from both SD and eMMC,
and the pins of mmc controller booting from SD are also shared with
one of spi controllers.
So two configs are need for these boot types:
1. mt7988_rfb_defconfig - SPI-NOR, SPI-NAND and eMMC
2. mt7988_sd_rfb_defconfig - SPI-NAND and SD

net: mediatek: connect switch to PSE only when starting eth is requested
So far the switch is initialized in probe stage and is connected to PSE

- Still initialize switch in probe stage, but disconnect it with PSE
- Connect switch with PSE on eth start
- Disconnect on eth stop

pinctrl: mediatek: convert most definitions to const
There exists a situation of the mediatek pinctrl driver that may return
wrong pin function value for the pinmux driver:
- All pin function arrays are defined without const
- Some pin function arrays contain all-zero value, e.g.:
static int mt7622_spi_funcs[] = { 0, 0, 0, 0, 0, 0, };
- These arrays will be put into .bss section during compilation
- .bss section has no "a" attribute and does not exist in the final binary
file after objcopy.
- FDT binary blob is appended to the u-boot binary, which occupies the
.bss section.
- During board_f stage, .bss has not been initialized, and contains the
data of FDT, which is not full-zero data.
- pinctrl driver is initialized in board_f stage, and it will get wrong
data if another driver is going to set default pinctrl.
Since pinmux information and soc data are only meant to be read-only, thus
should be declared as const. This will force all pinctrl data being put
into .rodata section. Since .rodata has "a" attribute, even the all-zero
data will be allocated and filled with correct value in to u-boot binary.
In u-boot we don't use IRQ. Instead, we poll busy bit in SPI_STATUS.
However these IRQ enable bits may be set in previous boot stage (BootROM).
If we leave these bits not cleared, although u-boot has disabled IRQ and
nothing will happen, the linux kernel may encounter panic during
initializing the spim driver due to IRQ event happens before IRQ handler
is properly setup.
This patch clear IRQ bits to prevent this from happening.

hardware errors cause a complete lockup of the CPU (which eventually
results in an watchdog reset).
Put the I2C MPP pins into GPIO mode and use the i2c-gpio driver instead.
This uses a bit-banged implementation of an I2C controller and avoids
triggering the Errata.

i2c: i2c-gpio: Correctly handle new {sda, scl}-gpios bindings
gpio_request_list_by_name() returns the number of gpios requested.
Notably it swallows the underlying -ENOENT when the "gpios" property
does not exist.
Update the i2c-gpio driver to check for ret == 0 before trying the new
sda-gpios/scl-gpios properties.
