All Hatch variants so far embed static SPD data encoded within the
firmware image. However we wish the flexibility for romstage
implementations that allow for reading the SPD data dynamically over
SMBus.

This change adds support for variant_memory_sku() that allows variant
to return memory SKU ID. Current implementation of memory_sku() is
renamed to weak implementation of variant_memory_sku(). Functionally
this change should be the same as before for all hatch variants. This
function will be overriden by helios in a follow-up CL.

Move the memory strap gpios to variant/gpio.h, as the memory straps
are different for helios.

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().

MEM_CH_SEL is used to indicate whether we are on a single or dual
channel device, where MEM_CH_SEL = 1 for single channel skus and
MEM_CH_SEL = 0 for dual channel skus. Initialize single_channel field
(from GPP_F2), which will in turn initialize MemorySpdPtr pointers in
cannonlake soc code. In the first build, we did not use GPP_F2, so we
need to add an internal pulldown as those early devices were all dual
channel devices.

BRANCH=None
TEST=Boot into current boards and ensure that we have 2 channels as expected
Also, verify that GPP_F2 is set to 0.

This change reads DRAM part number from EEPROM if available and
returns it using the SoC callback (mainboard_get_dram_part_number).
