Convert the hisilicon,hi6220-dsi binding to DT schema format. It's a
straight forward conversion.

-Device-Tree bindings for DesignWare DSI Host Controller v1.20a driver
-
-A DSI Host Controller resides in the middle of display controller and external
-HDMI converter or panel.
-
-Required properties:
-- compatible: value should be "hisilicon,hi6220-dsi".
-- reg: physical base address and length of dsi controller's registers.
-- clocks: contains APB clock phandle + clock-specifier pair.
-- clock-names: should be "pclk".
-- ports: contains DSI controller input and output sub port.
-  The input port connects to ADE output port with the reg value "0".
-  The output port with the reg value "1", it could connect to panel or
-  any other bridge endpoints.
-  See Documentation/devicetree/bindings/graph.txt for more device graph info.
