vendorcode/amd: Unify Porting.h across all targets

This requires to also unify the calling convention for
AGESA functions from
 AGESA_STATUS (*agesa_func)(UINT32 Func, UINT32 Data, VOID *ConfigPtr)
to
 AGESA_STATUS (*agesa_func)(UINT32 Func, UINTN Data, VOID *ConfigPtr)

On systems running 32bit x86 code this will not make a difference as
UINTN is uintptr_t which is 32bit on these machines.
