Silicon/Socionext: add PlatformPeilib implementation for SynQuacer
Create a specialized PlatformPeiLib implementation that invokes the
platform specific firmware interface (currently, just a data structure
left in SRAM) to set the ARM standard PcdSystemMemoryBase|Size PCDs,
and expose the information via a newly added DramInfo PPI.
