[PATCH] ALSA: HDA: Fix Realtek automute Line Out -> Internal Speaker

This patch is a fixup for 3.0 and 3.1 only - 3.2 has a refactored 
automute for Realtek.

Takashi, could you ack this patch? I think Greg usually wants that 
before applying.

Subject: [PATCH] ALSA: HDA: Fix Realtek automute Line Out -> Internal Speaker

In kernels 3.0 and 3.1, no automute control was created unless
Headphone pins were present. This patch enables automute for the
case where there are just Line Out and Speaker pins.
