drm/msm: add DSI support for sc7180
Add support for v2.4.1 DSI block in the sc7180 SoC. 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).
