soc/intel/common: Move PMC EPOC related code to Intel common code
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.
