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].

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.

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 copyright holder? - 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.
