Bug description:
[Impact]
After HDA controller gets suspended and resumed, no MSI interrupt raised
when plugging headset to the audio jack.
[Fix]
Power up the Realtek codec when HDA controller runtime resumes.
[Test]
1) Make sure both codec and HDA controller are runtime suspended.
2) Runtime resume the HDA controller without runtime resume the codec.
3) Plug a headset and see if the system can detect anything.
With the fix applied, we can see azx_interrupt() is working again by
using ftrace.
[Regression Potential]
If there's any system that is not affected by this issue, runtime-resume
the HDA controller will take a slightly longer time. It's rather
unlikely, since _all_ systems with Realtek codec we tested have this
issue, regardless of AMD or Intel.
