trogdor: Modify DDR training to use mrc_cache
Currently, trogdor devices have a section RO_DDR_TRAINING that is used to store memory training data. Changing so that we reuse the same mrc_cache API as x86 platforms. This requires renaming RW_DDR_TRAINING to RW_MRC_CACHE and removing RO_DDR_TRAINING in the fmap table. BUG=b:150502246 BRANCH=None TEST=FW_NAME="lazor" emerge-trogdor coreboot chromeos-bootimage Make sure that first boot after flashing does memory training and next boot does not. Boot into recovery two consecutive times and make sure memory training occurs on both boots.
