drm/msm: add timestamp param
We need this for GL_TIMESTAMP queries. Note: currently only supported on a4xx.. a3xx doesn't have this always-on counter. I think we could emulate it with the one CP counter that is available, but for now it is of limited usefulness on a3xx (since we can't seem to do time-elapsed queries in any sane way with the existing firmware on a3xx, and if you are trying to do profiling on a tiler you want time-elapsed). We can add that later if it becomes useful. Signed-off-by: Rob Clark <robdclark@gmail.com>
