soc/intel/cannonlake: Initialize PMC controller PMC controller gets hidden during FSP-Silicon initialization using sideband interface on CannonLake platform. Hence accessing PWRMBASE using PCI config space will return invalid BAR value as 0xFFFFF000. Also PMC PCI driver will not be able to initialize PMC controller as its not showing over PCI bus. coreboot PCI enumeration log shows: PCI: Static device PCI: 00:1f.2 not found, disabling it. This patch ensures PMC controller is getting initialized using boot state machine right after FSP Silicon Init returns (BS_DEV_INIT_CHIPS/ BS_ON_EXIT). TEST=Ensures PWRMBASE address is 0xFE000000 and PMC controller is getting initialized during BS_DEV_INIT_CHIPES/BS_ON_EXIT.
