sc7180: Fix prefill requirement and correct the fetch start check
With Innolux panel timings, the fetch_start has evaluated to be more than
v_total which is invalid. Add a check to accommodate the extra h_total addition
in fetch_start calculation. Secondly, made the prefill line requirement
same as Kernel driver.
