drm/amdgpu/gfx10: set UNORD_DISPATCH in compute MQDs

[ Upstream commit 03ff6d7238b77e5fb2b85dc5fe01d2db9eb893bd ]

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.  Updated firmware is also
required for AQL.
