mb/google/skyrim/var/skyrim: Add supported memory parts
Add supported memory parts and generate the associated DRAM part ID.
Also for MT62F2G32D8DR-031 WT:B memory part, add a custom SPD that
configures the DRAM speed at 5500 MHz. Use this custom SPD until that
part can operate at full speed (i.e. 6400 MHz).
BUG=None
TEST=Build Skyrim.
