[PATCH] drm/msm/dp: enable widebus on all relevant chipsets

From: Abhinav Kumar
Date: Thu Jul 11 2024 - 18:49:26 EST


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.
