[ALSA] Disable AC97 AUX and VIDEO controls for WM9705 touchscreen
This patch by Rodolfo Giometti disables the AC97 AUX and VIDEO controls
on the WM9705 when the touchscreen is selected as the AUX and VIDEO
lines are shared with the touch controller.
Changes:-
o Added AC97_HAS_NO_AUX flag
o Test for AC97_HAS_NO_AUX flag in snd_ac97_mixer_build()
o Sets AC97_HAS_NO_VIDEO and AC97_HAS_NO_AUX in patch_wolfson05() when
WM9705 touch driver is selected.
