ALSA: hda - Replace bus pm_notify with the standard runtime PM framework
Now the final bit of runtime PM cleanup: instead of manual
notification of the power up/down of the codec via hda_bus pm_notify
ops, use the standard runtime PM feature.
The child codec device will kick off the runtime PM of the parent
(PCI) device upon suspend/resume automatically. For managing whether
the link can be really turned off, we use the bit flags
bus->codec_powered instead of the earlier bus->power_keep_link_on.
flag. Each codec driver is responsible to set/clear the bit flag, and
the controller device can be turned off only when all these bits are
cleared.
