Bug description:
  [SRU Justification]

  [Impact]
  On some platforms with Cirrus CS8409 audio codec, the external headset will 
fail to be detected after system resume.

  [Fix]
  Cirrus released a new fix commit 65cc4ad62a9e ('ALSA: hda/cs8409: Set PMSG_ON 
earlier inside cs8409 driver'). It sets the power_state to ON before the 
unsolicited event arrives to make sure the jack detection can be invoked after 
resume.

  [Test]
  Plug-in an external headset in front headset port, suspend/resume the system 
then check whether the headset function works as expected.

  [Where problem could occur]
  Low. It only affect the platforms with Cirrus codec CS8409 which used to have 
problem.
