Besides, as the codec doesn't support EPSS, if we want to support runtime PM, simply add the AZX_DCAPS_PM_RUNTIME flag doesn't help. We must think out a method to ensure the driver enter pm runtime even the codec doesn't support.

Wait, is the controller for the generic codecs or dedicated to the
embedded HDMI?  In the latter case, AZX_DCAPS_INTEL_PCM_NOPM is anyway
wrong.  For HDMI, we use different flags.
