drivers/intel/fsp2_0: Introduce fsp print helper macros

Browse Source 
This patch introduces fsp print helper macros to print
`efi_return_status_t' with the appropriate format. These macros
are now used for fsp debug prints with return status

efi_return_status_t is defined as UINT64 or UNIT32 based on the
selected architecture

BUG=b:329034258
TEST=Verified on Meteor Lake board (Rex)
