[PATCH edk2-staging 14/20] IntelUndiPkg/XGigUndiDxe: redefine UNREFERENCED_nPARAMETER macros for GCC

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

Use (VOID) casts to silence unreferenced parameter warnings on GCC. The
existing macros generate 'statement with no effect' warnings instead,
which does not really help.
