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.

Also clean up cannonlake_memcfg_init.
The major changes include:
(1) Add enum 'mem_info_read_type' to spd_info.
(2) Add per-dimm-slot spd_info to cnl_mb_cfg.
(3) Setup memory config for each slot independently.
(4) Squash meminit_memcfg_spd().

Variants of Hatch need to accommodate single channel DDR. Also,
removing const modifier as we'll need to set these fields
incrementally now. For the single channel configuration, we set
MemorySpdPtr10 to 0. For the dual channel configuration, we set
MemorySpdPtr10 to MemorySpdPtr00.

Modify the previously SOC_CNL_LPDDR4_INIT to SOC_CNL_MEMCFG_INIT, to
make the infrasturture to handle both LPDDR4 and DDR4 cases in the
future. Consider the case of reading SPD from SMBus other than providing
SPD pointer directly.

TEST=Verify "./util/abuild/abuild -p none -t google/zoombini -x -a"
