	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.

2020-05-22	soc/intel/tigerlake: Provide SoundWire controller properties	Duncan Laurie
	The Intel Tigerlake SoundWire controller has 4 master links which are configured differently depending on the external crystal oscillator which is connected to the PCH. This function will read the PCH PMC EPOC register to determine the frequency and then fill out the master link entries with the correct table values. The frequency is also provided directly in a custom "ip-clock" property which will be added to the link descriptor and passed to the OS driver so it can know the clock rate of the master.
