[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.
