... and replace with the existing hda-core helper codes. This reduces lots of lines, finally.
Since struct hda_bus is now embedded into struct azx, snd_hda_bus_new() is moved and expanded from hda_codec.c to hda_controller.c, accordingly. Also private_free bus ops and private_data field are removed because we no longer need to point azx object from bus (we can use container_of())
The spin locks are consolidated into the single one, bus->reg_lock.
