It has been a while since ARM Trusted Firmware supported UniPhier SoC
family. U-Boot SPL was intended as a temporary loader that runs in
secure world. It is a maintenance headache to support two different
boot mechanisms. Secure firmware is realm of ARM Trusted Firmware
and now U-Boot only serves as a non-secure boot loader for UniPhier
ARMv8 SoCs.

The SCP (System Control Processor) or what we call STM (Stand-by
MPU) is integrated in LD4, Pro4, sLD8, LD6b, LD11, and LD20.
For these SoCs, show the information if STM is enabled.

Re-use of routines embedded in the Boot ROM requires a function
pointer table for each SoC. This is not nice in terms of the
maintainability in a long run.
Implement simple eMMC load APIs that are commonly used for LD11,
LD20, and hopefully future SoCs.

The current implementation has ugly switch statements here and there,
and duplicates similar code. Rework it using table lookups for SoC
data and reduce code duplication.
