drm/msm/dpu: add division of drm_display_mode's hskew parameter

Browse Source 
[ Upstream commit 551ee0f210 ]

Setting up the timing engine when the physical encoder has a split role
neglects dividing the drm_display_mode's hskew parameter. Let's fix this
since this must also be done in preparation for implementing YUV420 over
DP.
