There are many issues with SDMA across many generations of hardware.
A recent example is that gfx10.3 suffers from random GPU hangs if
userspace uses SDMA.

It's straightforward except that the amdgpu winsys had to be cleaned up
to allow this.
radeon_cmdbuf is inlined and optionally the winsys can save the pointer
to it. radeon_cmdbuf::priv points to the winsys cs structure.

- don't test 2 waves/SA
- create the compute shader only once per subtest
- use only 1 TIME_ELAPSED query per subtest
- don't invalidate sL0 (it's not used)
- don't invalidate L2 for L2_LRU to test L2 throughput
- don't flush the CS after every run
- remove unused min/max computation

The introduction of GCR_CNTL makes cache flush handling on gfx10
sufficiently different that it makes sense to just use a separate
function.
Since emit_cache_flush is called quite early during context init,
we initialize the pointer explicitly in si_create_context.

We already use GFX9 and I don't want us to have confusing naming
in the driver. GFXn naming is better from the driver perspective,
because it's the real version of the gfx portion of the hw. Also,
CIK means Bonaire-Kaveri-Kabini, it doesn't mean CI.
It shouldn't confuse our SDMA, UVD, VCE etc. code much. Those have
nothing to do with GFXn and they have their own version numbers.
