cr50: refactor rma mode into factory mode
We're doing a bit of refactoring to break out factory mode into its own
file. Now factory reset and rma reset will be two methods of entering
factory mode. Factory mode can be disabled with the disable_factory
vendor command.
Factory mode means all ccd capabilities are set to Always and WP is
permanently disabled. When factory mode is disabled, all capabilities
are reset to Default and WP is reset to follow battery presence.
This adds 56 bytes.
BUG=none
BRANCH=cr50
TEST=verify rma reset will enable factory mode.
