[media] Add proper audio support for Nova-S Plus with wm8775 ADC
This patch adds audio DMA capture and ALSA mixer elements for the line
input jack of the Hauppauge Nova-S-plus DVB-S PCI card. The Nova-S-plus
has a WM8775 ADC that is currently not detected. This patch enables
this chip and exports volume, balance mute and ALC elements for ALSA
mixer controls.
[mchehab@redhat.com: Changed the patch to only talk with wm8775 if board
info says so. Also, added platform_data support, to avoid changing the
behaviour for other boards, and fixed CodingStyle]
[awalls@md.metrocast.net: Changed patch to make the WM8775_GID defintion
bridge driver private and let the bridge driver set the value of
v4l2_subdev.grp_id.]
