v3d: request the kernel to flush caches when TMU is dirty
This adapts the v3d driver to the new CL submit ioctl interface that
allows the driver to request a flush of the caches after the render
job has completed. This seems to eliminate the kernel write violation
errors reported during CTS and Piglit excutions, fixing some CTS tests
and GPU resets along the way.
v2:
- Adapt to changes in the kernel side.
- Disable shader storage and shader images if the kernel doesn't
implement cache flushing.
Fixes CTS tests:
