The ARL requires that the GMA and NPU devices both be in D3Hot in order
for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition
to the intel_pmc_core driver attempted to do this by switching them to D3
in the init and resume calls of the intel_pmc_core driver.
The problem is the ARL-H/U have a different NPU device and thus are not
being properly set and thus S0iX does not work properly in ARL-H/U. This
patch creates a new ARL-H specific device id that is correct and also
adds the D3 fixup to the suspend callback. This way if the PCI devies
drop from D3 to D0 after resume they can be corrected for the next
suspend. Thus there is no dropout in S0iX.

As is the case on Meteor Lake, the Gaussian & Neural Accelerator (GNA)
device is powered by BIOS to D0 by default. If no driver is loaded, this

significant power consumption and decrease in batter life. Put the GNA
device in D3 by default if no driver is loaded for it.
