disp: msm: sde: update BW_INDICATION programing sequence

BW_INDICATION indication must be programed before BWI_THRESHOLD.
Otherwise, it will revert to legacy behaviour and rsc wakeup is
delayed by one vsync causing janks. In current code BW_INDICATION
is done after LM/SSPP programming and plane fence wait. Moved the
perf_crtc_update before this and just after ctl prepare configuration
to avoid chances of BW_INDICATION crossing BWI_THRESHOLD time.
