soc/intel/adl: Unhide PMC, IOM ACPI devices from OS
These were hidden because no Windows drivers existed, but now that
they do, the ACPI devices need to be visible in order for the
drivers to properly attach.
TEST=build google/banshee, boot Windows, verify Windows drivers
correctly attach to PCM/IOM devices.
