mb/google/volteer: implement mainboard_get_dram_part_num()
Implements mainboard_get_dram_part_num() to override dram part number with a part number read from CBI. BUG=b:146464098 TEST="emerge-volteer coreboot chromeos-bootimage", flash volteer, boot and log into kernel, execute "mosys memory spd print id" and verify that the memory part number from the cbi gets displayed properly.
