drm/msm: Make sure to detach the MMU during GPU cleanup
We should be detaching the MMU before destroying the address space. To do this cleanly, the detach has to happen in adreno_gpu_cleanup() because it needs access to structs in adreno_gpu.c. Plus it is better symmetry to have the attach and detach at the same code level. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
