link: EC reclaims fan control on AP shutdown
Previously, if the AP took fan control, the EC would never take it
back. This meant the EC would leave the fan off even if the system
was sitting at the INSERT screen or booted an alternate OS.
BUG=chrome-os-partner:15189
BRANCH=link
TEST=manual
- boot system
- from EC console, fanset 0
- faninfo shows fan at 0rpm
- from root shell, crossystem recovery_request=123 && reboot
- wait a few mins
- faninfo should show fan spinning again
