Fix missing HDMI Audio on another HP Desktop

[Kai-Heng Feng]

[Impact]
There's another HP desktop doesn't claim to support HDMI audio.

[Fix]
Add the system to HDMI force connect quirk list.

[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.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
