arch-specific code and proper errno error codes are not always returned.

Makefile: apply dynamic relocations for LLD
It seems that for aarch64, unless we apply dynamic relocations to the
location being relocated, we fail to boot.
As Fangrui notes:
For dynamic relocations using the RELA format (readelf -Wr), GNU ld
sets the initial content to r_addend; ld.lld doesn't do that by
default (needs --apply-dynamic-relocs).
Otherwise .rodata appears to be full of NUL-bytes before relocation,
causing crashes when trying to invoke the function pointers in
init_sequence_f from initcall_run_list().

examples: standalone: Fix build with LLVM toolchain
When building the standalone example with llvm, the link step fails:
examples/standalone/libstubs.o: In function `dummy':
include/_exports.h:10: undefined reference to `jt'
include/_exports.h:11: undefined reference to `jt'
include/_exports.h:12: undefined reference to `jt'
include/_exports.h:13: undefined reference to `jt'
include/_exports.h:14: undefined reference to `jt'
examples/standalone/libstubs.o:include/_exports.h:15:
more undefined references to `jt' follow
Indeed, the standalone libstubs.o does use the jt symbol, but it was
marked 'static' in stubs.c. It's strange how gcc builds are working.

usb: gadget: fastboot: detach usb on reboot commands
When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.
On some boards, such as Khadas VIM3L and SEI610, this is not the case.
We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
# echo b > /proc/sysrq-trigger
In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.
Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.
Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).
In drivers usb/host/{ehci,ohci}-generic.c, {ehci,ohci}_setup_phy() and
{ehci,ohci}_shutdown_phy() shares 95% of common code.
Factorize this code in new generic_{setup,shudown}_phy() functions.

usb: gadget: Clean up Makefile ifdeffery
Take the USB_ETHER ifdef block apart and make use of obj-$(VAR) instead
to include the source files in build. The duplicate CI_UDC entry is now
removed, the USB_DEVICE ifdef is now reduced to core.o ep.o addition,
the ether.o can be conditionally compiled in using USB_ETHER.
No functional change.

usb: Add missing guard around env_get() in usb_hub
The env_get() might be undefined in case ENV_SUPPORT is disabled,
which may happen e.g. in SPL. Add missing ifdef guard around the
env_get() to prevent build failure.
