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

Currently SPI bus id is used to map to the controller in order to set
the controller state. In certain platforms SPI bus id might not be
exactly the same as GSPI bus id. For example, in Intel platforms SPI bus
id 0 maps to fast spi i.e. SPI going to the flash and SPI bus id 1 .. n
map to GSPI bus id 0 .. n-1. Hence using SPI bus id leads to mapping to the
GSPI controller that is not enabled. Use the GSPI id bus so that the right
controller is set to active state. This fixes the regression introduced
