On older platforms, the base address for PMC was hardcoded in the
driver. Newer platforms can now retrieve the base address from SSRAM.
Use SSRAM to discover pwrm base address on Meteor Lake platform. If
this method fails, it will fall back to the hardcoded value.

On platforms with multiple PMCs, additional PMC devices are discovered
in the SSRAM device associated with the primary PMC. Add support for
discovering PMC devices from SSRAM. Use PMC devid to assign the
corresponding register map.

An earlier commit placed some driverless devices in D3 during boot so that
they don't block package cstate entry on Meteor Lake. Also place these
devices in D3 after resume from suspend.

On Meteor Lake, the GNA, IPU, and VPU devices are booted in D0 power state
and will block the SoC from going into the deepest Package C-state if a
driver is not present. Put each device in D3hot if no driver is found.
