Add support for updating MCU. Use the fw_update API provided

the reboot function required by the API.

Also update the top-swap boundary to 128K which is the default
setting in the descriptor.

BUG=NA
BRANCH=NA
TEST=Build and boot hatch. Also test the ucode update flow with
supporting changes in hatch mainboard.
