Subject[v2] drm/msm: add support for 2.4.1 DSI version for sc7180 soc
Date
Modify commit text to indicate DSI version and SOC detail

Changes in v1:
-Modify commit text to indicate DSI version and SOC detail(Jeffrey Hugo).
-Splitting visionox panel driver code out into a
different patch(set), since panel drivers are merged into
drm-next via a different tree(Rob Clark).
Changes in v2:
-Update commit text accordingly(Matthias Kaehlcke).
