[PATCH 3/3] platform/x86/intel/pmc/arl: Put GNA device in D3

From: David E. Box
Date: Wed Feb 21 2024 - 16:12:55 EST


To unblock Package C state entry, put the GNA device in D3 by default if no
driver is loaded for it.

Fixes: 83f168a1a437 ("platform/x86/intel/pmc: Add Arrow Lake S support to intel_pmc_core driver")
