Fix AMDGPU: No video output and system hangs with two monitor (dGPU: W6400)

[koba]

[Impact]
There's possibility that system will hang and no video output of two external monitor with dGPU W6400

Monitor 1: ASUS ProArt PA238Q (FHD)
Monitor 2: Dell P2415Q (4K)

[Fix]
Introduce the dmi quirk in amdgpu,
and add dmi quirks to bypass the affected machine.

[Test Case]
Two ways to verify

Method 1:
1. Cold boot with ASUS
2. Attach Dell monitor. ASUS is primary.
3. Switch display mode to single ASUS
4. Switch disaply mode back to Joing Displays. ASUS is primary

Method 2:
1. Cold boot with two monitors. ASUS is primary
2. Unplug the DP cable of Dell monitor from DUT and wait for few seconds
3. Plug it back to DUT

[Where problems could occur]
Low, add a dmi quirk to bypass the target machine.

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

This bug is awaiting verification that the linux-oem-5.17/5.17.0-1019.20 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
