disp: msm: sde: use fixed prefill lines in rscc static wakeup calculation

Browse source 
In dual display during bootup, panel prefill lines may be used in
configuring rscc static wakeup due to ongoing autorefresh in secondary
display. Due to this, there can be a case when transfer time for the
commit is greater than the static wakeup calculated when panel has
large prefill lines(vbp + vpw + vfp) causing janks on primary when
secondary display enters idle and primary display is running. Add changes
to use default_prefill_lines for configuring static wakeup during bootup
when rsc is in clk state. For vid state only, panel prefill
lines will be taken into account for rsc static wakeup calculation.
