ALSA: hda - Move the dsp loader to hda_controller
Moving the DSP loading functionality to hda_controller.c means that
the dsp lock doesn't need to be shared in hda_intel and
hda_controller. The forthcoming platform driver doesn't need the DSP
loading code, but sharing it doesn't hurt.
Tested on Chromebook Pixel's ca0132 that uses the DSP loader.
