samus: Ensure PD controller is in RO mode for recovery
In order to not break FAFT, and to have a quicker recovery
mode boot, reboot the PD controller into RO image in romstage.
This is done before the EC since rebooting the EC into RO will
also reboot the host.
BUG=chrome-os-partner:30079
BRANCH=none
TEST=boot samus EVT into recovery with 'dut-control power_state:rec'
and ensure that the PD controller is rebooted to RO in romstage.
