Bug description:
  ===SRU Justification===
  AMD Raven Ridge's audio controller doesn't get runtime suspended. It consumes 
unnecessary power.

  With the patch, it can get runtime suspended and save ~1W for the system.
  It can also get runtime resumed correctly when doing audio input/output.

  Add AZX_DCAPS_PM_RUNTIME flag to let sound subsystem know it supports runtime 

  [Regression Potential]
  Low. This change limits to Raven Ridge's audio controller.
