[PATCH edk2-platforms 02/14] Silicon/Synquacer: add MemoryInitPeiLib implementation

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

Replace the common MemoryInitPeiLib implementation with one that does
not remove the primary FV from the memory map. This is a waste of
memory and TLB entries, given that the OS can no longer use a 1 GB
block mapping to map this memory.

Since we have our own implementation now, there is no point in using
ArmPlatformLib's GetVirtualMemoryMap() implementation, and we can
simply declare and map the regions directly.
