Public bug reported:
[Impact]
Intel GPU hang on 6.1 stable kernel in login menu after boot.
[Fix]
Add missing DC_OFF power domain for GPU.
[Test]
Tested on Intel RPL iGPU and DG2 GPU.
[Where problems could occur]
Low risk, the fix is in 6.2-rc1,
the issue is only reproduced on oem-6.1 kernel,
not reproduced on jammy kernel.
So SRU for oem-6.1 only.
