soc/intel/*/pmc: Add finalize
operation for pmc
This patch implements the required operations to perform prior to booting to OS using coreboot native driver when platform decides to skip FSP notify APIs, i.e., Ready to Boot and End Of Firmware. Additionally, move the PMCON status bit clear operation to `.final` ops to cover any such chances where FSP-S Notify Phase or any other later boot stage may request a global reset and PMCON status bit remains set. BUG=b:211954778 TEST=Able to build brya with these changes.
