In addition to that, HDA may not be able to be runtim suspended again after resume from hibernation. [Fix] Prevent the SOF driver touches codec during system suspend, and properly refcount the PM usage counter. [Test] On an affected SOF system, it takes 5 mins to suspend. On another affected HDA system, S4 resume causes high power consumption becuase HDA controller can't be runtime suspended. Both issues are gone by applying these patches. [Where problems could occur] If somehow any laptop depends on the old behavior to work properly, this can break them. It's highly unlikely though.
