2022-11-08soc/intel: Use `PWRMBASE` over static `Index 0` for PMCSubrata Banik

2022-02-15soc/intel/*/pmc: Add `finalize` operation for pmcSubrata Banik
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.

2021-10-17soc/intel: implement ACPI timer disabling per SoC and drop common codeMichael Niewöhner
Since it's just a one-liner, implement disabling of the ACPI timer in soc code. This reduces complexity.

2021-10-17soc/intel: move disabling of PM Timer to SoC PMC codeMichael Niewöhner
Move disabling of PM Timer to SoC PMC code. The original reason for placing that in `finalize` [1] was FSP hanging due to use of the PM timer without enabling timer emulation first in coreboot, which was added later [2].

2021-06-30soc/intel/common: Move PMC EPOC related code to Intel common codeLean Sheng Tan
Move PMC EPOC related code to intel/common/block because it is generic for most Intel platforms and ADL, TGL & EHL use it. Add a kconfig 'PMC_EPOC' to guard this common EPOC code. The PMC EPOC register indicates which external crystal oscillator is connected to the PCH. This frequency is important for determining the IP clock of internal PCH devices.
