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

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.
