soc/intel/{adl,tgl}: Set PMC ACPI device to hidden/on

This prevents Windows from displaying the PMC device in Device Manager
as an unknown device with no driver available, and brings Alderlake
and Tigerlake in line with Meteorlake and Pantherlake.

TEST=build/boot Win11 on starlabs/starlite_adl, verify PMC device
not shown as unknown device in Device Manager.
