Summary

The Intel Cannon Lake PCH is used on CPUs like Intel Whiskey Lake, and this patch allows HD Audio to work on these platforms.

Tested on the HP Spectre x360 13-p0043dx.

Inspired by Linux commit 2357f6f00098a437f9de084c3c34254d20dea789.

Bugzilla: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240574

Test Plan
  1. Get a system with Intel Cannon Lake PCH (e.g. I used a HP Spectre x360 13-p0043dx, but a X390/T490/X1C7 ThinkPad model should work as well, I can't test on a ThinkPad because I don't own one).
  2. Apply this patch to a source tree (CURRENT)
  3. Play something (e.g. YouTube video). Audio should work

Nice, that it works.

This looks good to my eye. Don't know if it will work...
