soc/intel/tigerlake: Enable ACPI support for PMC core OS driver
PMC core driver in OS 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, a required ACPI device,
to support that PMC core driver in tigerlake platform.
BUG=b:146236297

TEST="Build and flash volteer and verify it boots to kernel.
Checked for valid files under /sys/kernel/debug/pmc_core."
