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.
