Star Zeng 364f63c065 SourceLevelDebugPkg/DebugCommLibUsb3Pei: Make sure alloc physical mem 
PI 1.6 has supported pre permanent memory page allocation,
to make sure the allocated memory is physical memory for DMA,
the patch is to check memory discovered PPI installed or not first
before calling AllocatePages.
