drm/msm/sde: update kickoff sequence for command mode

Current command mode sequence configures the ctl_start
on primary controller for frame "N" and does not wait
for any event before updating LM/SSPP for frame "N+1".
This causes the pingpong timeout issue with rsc solver
mode. This patch updates the kickoff sequence with
ctl prepare configuration and ctl_start interrupt wait
before allowing to program the LM/SSP for frame "N+1".
