dt-bindings: display: Convert ingenic,lcd.txt to YAML
Convert the ingenic,lcd.txt to a new ingenic,lcd.yaml file. In the process, the new ingenic,jz4780-lcd compatible string has been added. v2: Add info about IPU at port@8 v3: No change Signed-off-by: Paul Cercueil <paul@crapouillou.net> Reviewed-by: Rob Herring <robh@kernel.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200716163846.174790-2-paul@crapouillou.net

-Ingenic JZ47xx LCD driver
-
-Required properties:
-- compatible: one of:
- * ingenic,jz4740-lcd
- * ingenic,jz4725b-lcd
- * ingenic,jz4770-lcd
-- reg: LCD registers location and length
-- clocks: LCD pixclock and device clock specifiers.
- The device clock is only required on the JZ4740.
-- clock-names: "lcd_pclk" and "lcd"
-- interrupts: Specifies the interrupt line the LCD controller is connected to.

-Example:
-
-panel {
- compatible = "sharp,ls020b1dd01d";
-
- backlight = <&backlight>;
- power-supply = <&vcc>;
-
- port {
- panel_input: endpoint {
- remote-endpoint = <&panel_output>;
- };
- };
-};
-

-lcd: lcd-controller@13050000 {
- compatible = "ingenic,jz4725b-lcd";
- reg = <0x13050000 0x1000>;

- interrupt-parent = <&intc>;
- interrupts = <31>;
-
- clocks = <&cgu JZ4725B_CLK_LCD>;
- clock-names = "lcd";

- port {
- panel_output: endpoint {
- remote-endpoint = <&panel_input>;
