platform/x86/intel/ifs: Gen2 scan image loading
Scan image loading flow for newer IFS generations are slightly different
from that of current generation. In newer schemes, loading need not be
done once for each socket as was done in gen0.
Also the width of NUM_CHUNKS bitfield in SCAN_HASHES_STATUS MSR has
increased from 8 -> 16 bits. Similarly there are width differences for
CHUNK_AUTHENTICATION_STATUS too.
Further the parameter to AUTHENTICATE_AND_COPY_CHUNK is passed
differently in newer generations.
