soc/intel/common: Implement power-failure-state handling
This is a consolidation of the respective feature in `soc/intel/*lake/`,
including additional support for MAINBOARD_POWER_STATE_PREVIOUS.
For the latter, firmware has to keep track of the `previous` state. The
feature was already advertised in Kconfig long ago, but not implemented.
SoC code has to call pmc_set_power_failure_state() at least once during
boot and needs to implement pmc_soc_set_afterg3_en() for the actual
register write.
