msm: mdss: fix SW TE for dynamic resolution change cases
The Tear check sync cfg height, in case of SW TE is calculated based
on panel's height and vertical porch values. Simulator panels has the
capability to change the panel resolution after bootup, which would
require recalculation of tear check height. Fix the sync cfg height to
be set right for all cases.
