[ALSA] hda-codec - Add independent headphone volume control

This patch addes the support of the independent 'Headphone' volume
control to the generic codec parser. Some codecs (e.g. Conexant)
have separate connections to the headphone and the independent amp
adjustment is needed.

Just make sure you don't break the headphone jack on some systems.
The headphone jack on the Panasonic T5 didn't work until recent kernels
(probably this was the thing that made it work).

Make sure that you unmuted both Master and Headphone volumes (if you
have).
With this patch, you may have now two individual controls while the
older version has only one.
