Changes since v7:
- Re-factored the patch to only include DAPM for existing IOs.
(i.e. removed DAPM support for AUX, line outs etc. This will be
added via other patches which add actual support for those IOs)
Changes since v3:
- Added missing routes for In-mixer left and right
- Added comment explaining rational behind use of STANDBY registers
Changes since v1:
- used supply widget for mic bias
- removed mic bias hookup
- assigned dapm widgets and routes in card struct
- removed explicit setting of default mixer settings
- removed explicit setting of ios to standby mode
