drm/radeon/kms: enable UVD as needed (v9)
When using UVD, the driver must switch to a special UVD power
state. In the CS ioctl, switch to the power state and schedule
work to change the power state back, when the work comes up,
check if uvd is still busy and if not, switch back to the user
state, otherwise, reschedule the work.
Note: We really need some better way to decide when to
switch out of the uvd power state. Switching power states
while playback is active make uvd angry.
V2: fix locking.
V3: switch from timer to delayed work
V4: check fence driver for UVD jobs, reduce timeout to
1 second and rearm timeout on activity
v5: rebase on new dpm tree
v6: rebase on interim uvd on demand changes
v7: fix UVD when DPM is disabled
v8: unify non-DPM and DPM UVD handling
v9: remove leftover idle work struct

drm/radeon/cik: Add support for compute queues (v4)
On CIK, the compute rings work slightly differently than
on previous asics, however the basic concepts are the same.
The main differences:
- New MEC engines for compute queues
- Multiple queues per MEC:
- CI/KB: 1 MEC, 4 pipes per MEC, 8 queues per pipe = 32 queues
- KV: 2 MEC, 4 pipes per MEC, 8 queues per pipe = 64 queues
- Queues can be allocated and scheduled by another queue
- New doorbell aperture allows you to assign space in the aperture
for the wptr which allows for userspace access to queues

drm/radeon: add a reset work handler
New asics support non-privileged IBs. This allows us
to skip IB checking in the driver since the hardware
will check the command buffers for us. When using
non-privileged IBs, if the CP encounters an illegal
register in the command stream, it will halt and generate
an interrupt. The CP needs to be reset to continue. For now
just do a full GPU reset when this happens.
