drm/msm: Enable per cmdstream profiling for the user
If the user provides a profile buffer identified with a buffer type
MSM_SUBMIT_CMD_PROFILE_BUF, then the driver records the kernel clock
time and gpu ticks at the time of cmdstream submission, and the GPU
records the ticks just before the start of the cmdstream execution and
right after the end of the cmdstream execution.
