Bug description:
[Impact]
If the codec is in rt_suspend while the controller is in rt_resume,
all audio jacks can't detect hotplug.
[Fix]
Backport a upstream patch, this will enable WAKEEN in the period
between codec suspend and controller suspend.
[Test]
Booting the patched kernel, add snd_sof_pci.sof_pci_debug=0x1 in
the bootargs, plug the headset to the audio jacks, the system
could detect the plug in or plug out.
[Where problems could occur]
The patch enable the WAKEEN after codec is in rt_suspend, this
could affect the audio jack hotplug detection, if it introduces
regression, it will be on the audio jack detection, but this
possibility is very low, we already verified this patch on
many machines.
