Enable PD communication in RO for external display
This patch makes EC enable PD communication if it's running in
manual recovery mode. This is required to show recovery screen
on a type-c monitor.
This patch also makes EC-EFS ignore power availability. It will
make EC verify & jump to RW even if power is sourced by a barrel
jack adapter. This should allow depthcharge to show screens
(e.g. broken, warning) on a type-c monitor.
BUG=b:72387533
BRANCH=none
TEST=On Fizz with type-c monitor, verify
- Recovery screen is displayed in manual recovery mode.
- Critical update screen is displayed in normal mode.
- Warning screen is displayed in developer mode.
Monitors tested: Dingdong, Dell S2718D
