mb/google/octopus: Preserve MRC training data across firmware update
This change udpates FMAP to wrap MRC training data in RW_PRESERVE
section so that we don't lose the data when performing full firmware
updates on octopus.
BUG=b:117882029
TEST=Verified that chromeos-firmwareupdate doing full firmware update
preserves training data on octopus.
