[ALSA] hda: minor correction to fujitsu ALC260 initverbs

Modules: HDA Codec driver

Jonathan Woithe <jwoithe@physics.adelaide.edu.au>

The following patch changes the initverbs associated with the output sum
widgets 0x08, 0x09 and 0x0a used with the fujitsu model in patch_realtek.c.
It is against alsa 1.0.11rc3.

Currently these widgets have their output muted, but a close reading of the
datasheet suggests that they don't actually have an output mute.  They have
an *input* mute for each of their two inputs and a single output gain. This
patch therefore activates the input mutes and zeros the output gain.  It has
not yet been tested but the above interpretation of the ALC260 datasheet
seems correct.
