ALSA: hda - Add channel-mode support to Realtek auto-parser

Browse source

This patch adds the support of "Channel Mode" enum control to Realtek
auto-parser.  When line-in or mic-in jacks are capable to output and
free DACs are available, the driver allows to switch to multi-channel
mode via "Channel Mode" enum switch, as already implemented in some
preset cases.

Not implemented in all Realtek codecs.  Currently, ALC880, 882, 861,
662 and the compatible codecs are supported.
