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.

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.

Now that the PMC device is marked as hidden in devicetrees, the device
callbacks can be used instead of BOOT_STATE_INIT_ENTRY callbacks.
Note that this moves PMC initialization from BS_DEV_INIT_CHIPS to
BS_DEV_ENUMERATE, which aligns with other Intel SoCs.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current

- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

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
903b40a8a4 ("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.

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.
