vendorcode/google/chromeos: Add mainboard hook before cr50 update
In order to allow the mainboard to configure the system before a
cr50 initiated update reset add a weak function that the mainboard
can override if necessary.
This will allow a board that would otherwise be configured to
stay off after an EC reset to instead power up after the reset and
not end up in a shut down state after a cr50 update.
BUG=b:121380403
TEST=update cr50 firmware on sarien and reboot
