Alex Deucher a59781bbe5 drm/radeon: add support for interrupts on CIK (v5) 
Todo:
- handle interrupts for compute queues

v2: add documentation
v3: update to latest reset code
v4: update to latest illegal CP handling
v5: fix missing break in interrupt handler switch statement

* CP.
* On CIK, gfx and compute now have independant command processors.

* GFX
* Gfx consists of a single ring and can process both gfx jobs and
* compute jobs. The gfx CP consists of three microengines (ME):
* PFP - Pre-Fetch Parser
* ME - Micro Engine
* CE - Constant Engine
* The PFP and ME make up what is considered the Drawing Engine (DE).
* The CE is an asynchronous engine used for updating buffer desciptors
* used by the DE so that they can be loaded into cache in parallel
* while the DE is processing state update packets.
*
* Compute
* The compute CP consists of two microengines (ME):
* MEC1 - Compute MicroEngine 1
* MEC2 - Compute MicroEngine 2
* Each MEC supports 4 compute pipes and each pipe supports 8 queues.
* The queues are exposed to userspace and are programmed directly
* by the compute runtime.
