mb/google/octopus: add support for new shared memory config
Allow for shared dram configuration by introducing a new table that collapses the common settings after removing the part numbers. When employing this scheme the part number comes from CBI. BUG=b:112203105 TEST=Placed part number in cbi. Faked out memory sku id. And enabled DRAM part num always in cbi. Everything checked out.
