Bug description:
[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.
