drm/msm/dp: enable widebus on all relevant chipsets
[ Upstream commit c7c412202623951dcfc22316f5255fd84fd56186 ]
Hardware document indicates that widebus is recommended on DP on all
MDSS chipsets starting version 5.x.x and above.
Follow the guideline and mark widebus support on all relevant
chipsets for DP.
