soc/amd/cezanne: Set Power state after power failure 

Configure the power state to return to when the power is re-applied
after power failure.

BUG=b:183739671
TEST=Build and Boot to OS in Majolica and Guybrush. By default when the
power fails the device turns on after power is re-applied. When the
POWER_ON_AFTER_POWER_FAILURE is disabled, the device remains off even
after the power is re-applied.
