Bug Description
[Impact]
There's an HP desktop doesn't claim to support HDMI audio.
[Fix]
Use a quirk list to force HDMI audio connection to ignore Connectivity
Bit, which is incorrectly set by BIOS.
[Test]
With the patch applied, we can find HDMI codec under /proc/asound/card0
and audio playback through HDMI works.
[Regression Potential]
This fix doesn't bring any functional change other than the targeted
platform. The platform in question is not on the market yet so the
risk of regression is minimal.
