cbtables: Add RAM config information

Browse Source 
This adds the RAM config code to the coreboot tables. The purpose is
to expose this information to software running at higher levels, e.g.
to print the RAM config coreboot is using as part of factory tests.

The prototype for ram_code() is in boardid.h since they are closely
related and will likely have common code.
