Now that tracking is wired up for potentially evictable GEM objects,
wire up shrinker and the remaining GEM bits for unpinning backing pages
of inactive objects.
Disabled by default for now, with an 'enable_eviction' module param to
enable so that we can get some more testing on the range of generations
(and iommu pairings) supported.

This reduces the spam in dmesg when we start hitting the shrinker, and
replaces it with something we can put on a timeline while profiling or
debugging system issues.

Technically the GMU specific one is a bit redundant, but it was useful
to track down a bug.

This was useful for debugging fps drops. I suspect it will be useful
again.

Add trace events to track the progress of a GPU submission
msm_gpu_submit occurs at the beginning of the submissions,
msm_gpu_submit_flush happens when the submission is put on
the ringbuffer and msm_submit_flush_retired is sent when
the operation is retired.
To make it easier to track the operations a unique sequence
number is assigned to each submission and displayed in each
event output so a human or a script can easily associate
the events related to a specific submission.
