soc/intel/cannonlake: Export function to set After G3 state
Export the SOC level function to set the After G3 state so it
can be changed by the mainboard. The setting will be restored
by a normal boot but in some circumstances coreboot wants to
ensure that it will be powered up again after a reset.
BUG=b:121380403
TEST=update cr50 firmware on sarien and reboot and ensure the
host does not power off after the cr50 initiated reset.
