soc/intel/common: Add ACPI support for PMC core OS driver

PMC core OS driver (intel_pmc_core.c in linux kernel) provides debug
hooks to developers and end users to quickly figure out why their
platform is not entering a deeper idle state such as S0ix.

This patch adds INT33A1 ACPI device to support PMC core OS
driver. Any SoC that supports this feature would include this asl file
to enable the support.
