A385 BootROM treats strapping configuration 0x3f as invalid. When booting
fails (e.g. because of invalid configuration) then BootROM fallbacks to
UART booting.
Detecting BootROM fallback to UART booting is implemented in U-Boot since
commit 2fd4284051 ("ARM: mach-mvebu: handle fall-back to UART boot").
So there is no need to define BOOT_FROM_UART_ALT constant and special
handling for it anymore, remove it.
This change effectively revers commit f3a88e2ca1 ("arm: mvebu: fix boot
from UART on ClearFog Base").

The Clearfog devices have only one SDHC device. This is either eMMC if
it is populated on the SOM or SDHC if not. The Linux device tree assumes
the SDHC case. Detect if the device is an eMMC and fixup the device-tree
so it will be detected by Linux.

Originally, the mmc aliases node was present in imx6qdl-pico.dtsi.
After the sync with Linux in commit d0399a46e7 ("imx6dl/imx6qdl:
synchronise device trees with linux"), the aliases node is gone as
the upstream version does not have it.
This causes a boot regression in which the eMMC card cannot be found anymore.
Fix it by passing the alias node in the u-boot.dtsi file to
restore the original behaviour where the eMMC (esdhc3) was
mapped to mmc0.

To fit the DBD_EN fused part, we re-design the TRDC and XRDC assignment.
M33 will be the TRDC owner and needs to configure TRDC. A35 is the
XRDC owner, ATF will configure XRDC.
The handshake between U-boot and M33 image is used to sync TRDC and
XRDC configuration completion. Once the handshake is done, A35 and M33
can access the allowed resources in others domain.
The handshake is needed when M33 is booted or DBD_EN fused, because both
cases will enable the TRDC. If handshake is timeout, the boot will hang.
We use SIM GPR0 to pass the info from SPL to u-boot, because before the
handshake, u-boot can't access SEC SIM and FSB.
