BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3385

A VS2012 build fails with a cast conversion warning when the SEV-ES work
area PCD is cast as a pointer to the SEV_ES_AP_JMP_FAR type.

When casting from a PCD value to a pointer, the cast should first be done
to a UINTN and then to the pointer. Update the code to perform a cast to
a UINTN before casting to a pointer to the SEV_ES_AP_JMP_FAR type.
