disp: msm: sde: fix video mode prefill lines for RSCC

Browse Source 
The RSCC static wakeup and the bandwidth trigger for
the downvotes are based on the prefill lines. Reduce
the prefill lines based on the panel vertical front
porch to avoid issuing bw downvotes during active
region of the previous frame.
