ALSA: hda - Add hda_controller.c and move pcm ops from hda_intel Pull the pcm_ops and the functions they use into a new hda_controller file. This is done to allow for other hda implementations besides PCI to use the same ops. The hda_controller file will house functionality related to HDA but independent of the bus used to talk to the controller. This currently shares dsp locking across the two files. This will be remedied in a following commit. Signed-off-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Make position_fix as generic callback ... and move most parts into hda_intel.c from the generic controller code. This is a clean up, and there should be no functional change by this patch. Now, struct azx obtains the generic callbacks for getting the position and the delay. As default NULL, posbuf is read. These replace the old position_fix[], and each is implemented as a callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Pull pages allocation to hda_controller Pull allocation from first_init to a new function in hda_controller.c. Short term this will allow the dsp loader to be moved as well.
