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/{skl,cnl,dnv}: disable PM ACPI timer if chosenMichael Niewöhner
Disable the PM ACPI timer during PMC init, when `USE_PM_ACPI_TIMER` is disabled. This is done to bring SKL, CNL, DNV in line with the other platforms, in order to transition handling of the PM timer from FSP to coreboot in the follow-up changes. For SKL and CNL, this temporarly redundantly disables the PM Timer, since FSP does that, too. This redundancy is resolved in the follow-up.

2019-07-07soc/intel/cannonlake: Use SA_DEV_ROOT instead of PCH_DEV_PMCFurquan Shaikh
PMC device gets hidden from PCI bus after FSP-S call. Thus, it gets removed from the root bus as leftover unused device. With change 903b40a8a46 ("soc/intel: Replace uses of dev_find_slot()"), all uses of dev_find_slot() were replaced by pcidev_path_on_root() which relies on scanning of root bus to find the requested device. Since PMC device is removed from the root bus, pcidev_path_on_root() returns NULL for it thus resulting in configuration being skipped for the PMC ultimately resulting in S3 failures. Since the PCH_DEV_PMC was just used to get to chip config, this change replaces the use of PCH_DEV_PMC with SA_DEV_ROOT. BUG=b:136861224 TEST=Verified that S3 works fine on hatch.

2019-02-27soc/intel/cannonlake: Disable ACPI mode as part of pmc_soc_initFurquan Shaikh
PMC initialization on Cannon Lake happens earlier in the boot sequence than other SoCs because FSP-Silicon init hides PMC from PCI bus. As ACPI disabling was done as part of PMC init, it was being called earlier than what other SoCs do. This resulted in a different order of events for some drivers e.g. ChromeOS EC. In case of ChromeOS EC, it ended up clearing EC events (which happens as part of ACPI disabling in SMM) before logging any events of interest that happen during mainboard initialization. This change moves the call to disable ACPI to pmc_soc_init just like other SoCs to keep the order of events more aligned. BUG=b:126016602 TEST=Verified that EC panic event gets logged to eventlog correctly.
