Nami: Disable powering off EC on cr50 update 

Nami doesn't support wakeup from hibernation by CR50. This causes the
device to remain turned off after CR50 update.

This patch disables turning off EC on cr50 update. CR50 resets the
whole system. So, 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.
