soc/intel/cannonlake: Support different SPD read type for each slot

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().
