cr50: Allow boards to disable powering off EC on cr50 update

This patch allows boards to disable turning off EC on cr50 update.
If CR50 resets the whole system, an EC reset is not required.

TEST=gsctool -a -u /media/removable/cr50.bin && reboot
Verify EC reboots. AP prints 'Waiting for CR50 reset to pick up update'
then reboots.
