      Send <Request ARC Termination> when Standby · ddc4753a

      [Description]
      In aosp/1313995, we propose to disable ARC at first, in case that
      AVR doesn’t response to <Request ARC Termination> during standby
      and ARC pin is not disabled.
      However, the proposed CL made TV never send <Request ARC Termination>
      during standby process, which is not expected.
      
      We still need to disable ARC Pin without waiting for <Termination ARC>
      sent from AVR. However, this could be done by calling
      enableAudioReturnChannel() of HdmiControlService directly after
      RequestArcTerminationAction is started, making sure that
      <Request ARC Termination> could be sent correctly by TV when ARC
      was enabled
      
      Note that after this modification, TV could receive <Terminate ARC>
      after AVR deviceInfo is cleared. In this case, a new AVR deviceInfo
      with physical address=0xFFFF is added by HdmiCecNetwork.
      As a result, we also add error handling in enableAudioReturnChannel
      for such case.
      
      [Test Report]
      1. Connect Denon AVR-3500H
      - TV standby off/on, ARC is okay
      - TV CEC off/on, ARC is okay.
