soc/intel/cannonlake: Do not read SPD again if index hasn't changed
With the recent refactoring of memory configuration in
CB:32513 ("soc/intel/cannonlake: Support different SPD read type for
each slot"), meminit_cbfs_spd_index ends up reading SPD from CBFS for
each slot. However, for mainboards that use the same SPD index for
each slot this is unneccessary. This change adds a check to see if
spd_data_ptr is not NULL and current spd index is the same as the last
call to decide if SPD read from CBFS should be skipped.
TEST=Verified that SPD gets read only once on hatch.
