drm/amd: set CP_HQD_PQ_CONTROL.SCOPE for PM4 and KCQs on GFX 12.1

Browse source

The previous change set CP_HQD_PQ_CONTROL.SCOPE=3 (SYSTEM) only for KFD
AQL queues, but PM4 queues and the kernel-managed compute (KCQ) queues
can also use non-coherently cached ring buffers and hit the same
stale-packet problem.

Set the scope for both PM4 queues and KCQs as well.
