drm/msm: add rd logging debugfs
To ease debugging, add debugfs file which can be cat/tail'd to log
submits, along with fence #. If GPU hangs, you can look at 'gpu'
debugfs file to find last completed fence and current register state,
and compare with logged rd file to narrow down the DRAW_INDX which
triggered the GPU hang.
