This patch allows boards to disable turning off EC on cr50 update.
If CR50 resets the whole system, an EC reset is not required.
BUG=b:112604277
BRANCH=none
TEST=gsctool -a -u /media/removable/cr50.bin && reboot
Verify EC reboots. AP prints 'Waiting for CR50 reset to pick up update'
then reboots.

This patch makes AP send EC_REBOOT_HIBERNATE_CLEAR_AP_OFF, which makes
EC clear AP_OFF flag then hibernate.
This is needed to make Chromebox boot when cr50 toggles the EC's reset
line after TURN_UPDATE_ON command.

Add printout before EC hibernates during a cr50 update to clarify that
failure is due to EC rather than cr50. Ran into a situation where DUT
shut down during cr50 update and the EC was the culprit.

The AP sends the Cr50 a request to enable the new firmware image. If
the new Cr50 image was found and enabled, the AP expects the Cr50 to
reset the device in 1 second.
While waiting for the Cr50 to reset, the AP logs a newly defined event
and optionally shuts down the system. By default the x86 systems power
off as shutting those systems down is not board specific.
BRANCH=gru,reef
BUG=b:35580805
TEST=built a reef image, observed that in case cr50 image is updated,
after the next reboot the AP stops booting before loading depthcharge,
reports upcoming reset and waits for it.
Once the system is booted after that, the new event can be found
in the log:
