Revert "ALSA: hda: call runtime_allow() for all hda controllers"

commit 07c9983b567d0ef33aefc063299de95a987e12a8 upstream.

This reverts commit 9a6418487b56 ("ALSA: hda: call runtime_allow()
for all hda controllers").

The reverted patch already introduced some regressions on some
machines:
 - on gemini-lake machines, the error of "azx_get_response timeout"
   happens in the hda driver.
 - on the machines with alc662 codec, the audio jack detection doesn't
   work anymore.
