soc/amd/common/fsp/dmi.c: Fill in mem manufacturer from CBI

Because the ChromeOS boards don't fill a manufacturer in for the memory
SPDs, that information isn't available from the FSP. We can get the
Manufacturer ID based on the memory name from CBI instead. Use this
information to fill in an ID so that the manufacturer name is available
in the SMBIOS information.

BUG=None
TEST=Look at dmidecode output
