[PATCH] IntelFsp2Pkg: Update Function header to support IA32/X64.

["Chiu, Chasel" <chasel.chiu@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4126

Common functions will have either 32bit or 64bit instances which
having different return code size. Function header should support both
scenarios.
