SDM845 DisplayPort output inop on DP Monitor and tears on HDMI.

Fixed
 - SDM845 does not support wide mode.
 - SDM845 does not need porch shift.

Verified functionality on SDM845.

James A. MacInnes (2):
  drm/msm/dp: Disable wide bus support for SDM845
  drm/msm/disp: Correct porch timing for SDM845
