  Internal worker function that returns the pointer to an EDK II Crypto\r
  Protocol/PPI.  The layout of the PPI, DXE Protocol, and SMM Protocol are\r
  identical which allows the implementation of the BaseCryptLib functions that\r
  call through a Protocol/PPI to be shared for the PEI, DXE, and SMM\r
  implementations.\r
\r
  This PEI implementation looks up the EDK II Crypto PPI and verifies the\r
  version each time a crypto service is called, so it is compatible with XIP\r
  PEIMs.\r
