2021-06-30soc/intel/common: Move PMC EPOC related code to Intel common codeLean Sheng Tan
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.

2021-06-04soc/intel/alderlake: Add PMC ACPI interfaceTim Wawrzynczak
This ACPI interface is required by e.g., the intel/common/pcie/rtd3 driver, which is used by some alderlake boards.

2021-05-07soc/intel/{adl,tgl,jsl}: Enable power button smi after BS_CHIPS_EXITKane Chen
On tgl, we noticed system hang if a shutdown is triggered before fsps. The dut is unable to shutdown properly due to tcss is stuck before tcss_init in fsps. This change enable power button smi on jsl, tgl, adl after fsps. it can also prevent a shutdown failure due to lack of fsps init on certain ip. BUG=b:186194102, b:186815114 TEST=Power on the system and pressing power button repeatedly doesn't cause the system hang during shutdown.
