mb/google/hatch,dedede,volteer: enable CHROMEOS_DRAM_PART_NUMBER_IN_CBI

Enable CHROMEOS_DRAM_PART_NUMBER_IN_CBI on hatch, dedede, and volteer
to use the common version of mainboard_get_dram_part_num().

Remove duplicate instances of mainboard_get_dram_part_num().

BUG=b:169789558, b:168724473
TEST="emerge-volteer coreboot && emerge-hatch coreboot &&
emerge-dedede coreboot" and verify it builds.
