Subject: [v1] dt-bindings: msm:disp: update dsi and dpu bindings

Updating bindings of dsi and dpu by adding and removing certain
properties.

Signed-off-by: Harigovindan P <harigovi@...eaurora.org>

Changes in v1:
        - Adding "ahb" clock as a required property.
        - Adding "bus", "rot", "lut" as optional properties for sc7180 device.
        - Removing properties from dsi bindings that are unused.
	- Removing power-domain property since DSI is the child node of MDSS
	  and it will inherit supply from its parent.
