Add EC_RO/EC_RW and WP_RO FMAP area for fw_updater and factory.
Add EC_RO/EC_RW and WP_RO FMAP area for fw_updater and factory.

EC_RO and WP_RO area are identical and should cover whole range needed to
be write-protected. While EC_RO is for legacy firmware updater, the WP_RO
is for future factory finalize test.

EC_RW is for fw_updater to update both A/B at once.
