From: Lydia Wang lydiawang@viatech.com.cn Subject: ALSA: VIA HDA: Fix independent headphone no sound issue.

Modify via_independent_hp_put() function to support VT1718S and VT1812 codecs, and fix independent headphone no sound issue.

This is also another issue that I'd like to fix before refactoring. There are many complaints about the silent output on VT codecs...
