drm/msm/dp: Add DisplayPort controller for SA8775P

Browse Source 
The Qualcomm SA8775P platform comes with 2 DisplayPort controllers
for each mdss, having different base offsets than the previous
SoCs. The support for all 4 DPTX have been added here, and
validation of only MDSS0 DPTX0 and DPTX1 have been conducted.
