[CML-S] Add-new-CNL-PCH-ID-seen-on-a-CML-platform

[Kent Lin]

[Impact]
Fix 'eDP powered off while attempting aux channel communication' warnings.

Add-new-CNL-PCH-ID-seen-on-a-CML-platform for https://bugs.freedesktop.org/show_bug.cgi?id=112051

Fix patch: https://bugs.freedesktop.org/attachment.cgi?id=145786

[Test case]
boot an affected machine, check that dmesg doesn't show the warning anymore

[Regression potential]
None, adds a pci-id

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[You-Sheng Yang (vicamo)]

This causes a regression that fails a certain platform while probing i915 devices. Detail mechanism remains unknown so far.

[You-Sheng Yang (vicamo)]

Also affects another platform with:

00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9bc8] (prog-if 00 [VGA controller])
        Subsystem: Dell Device [1028:09b4]

[You-Sheng Yang (vicamo)]

For comment #2, it's bug 1850768 and it's pciid:

00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9bc8] (prog-if 00 [VGA controller])
        Subsystem: Dell Device [1028:09a8]

For comment #3, it's bug 1852163.

[You-Sheng Yang (vicamo)]

The regression is reproducible when applied to v5.4-rc7.

[Timo Aaltonen (tjaalton)]

should be fixed by https://bugs.freedesktop.org/attachment.cgi?id=145843

[You-Sheng Yang (vicamo)]

Yes, verified that doesn't cause regression.
