3502ab5022 drm/amdkfd: Preserve cp_hqd_pq_control on update_mqd
When userspace applications call AMDKFD_IOC_UPDATE_QUEUE. Preserve
bitfields that do not need to be modified as they contain flags to
track queue states that are used by CP FW.

40318a2406 drm/amdgpu/gfx12: set UNORD_DISPATCH in compute MQDs
This needs to be set to 1 to avoid a potential deadlock in
the GC 10.x and newer.  On GC 9.x and older, this needs
to be set to 0. This can lead to hangs in some mixed
graphics and compute workloads.
