drm/msm: clean up inline rotator register dump

Add inline rotator register dump to sde dump so that
when inline use case causes panic, inline rotator hw
state is captured for analysis. Update sequence number
for proper tracking and output events as hex number to
trace log so that it is compatible with evtlog dump format.
