Bug description:
[SRU Justification]
[Impact]
Power consumption measurements are worse than Windows while using HW
accelerated video decoding.
[Fix]
Two commits from upstream v6.11-rc1 to add a unified queue to VCN for
more power saving.
[Test Case]
This involves attaching probes on mainboard and can only be performed
by AMD/ODM.
[Where problems could occur]
No.
[Other Info]
To apply to all kernels >= 6.8. Orauclar/Noble, OEM-6.8, OEM-6.11 are
nominated for fix.
