Subject: [RFC v3 1/8] dt-bindings: display: convert ingenic,lcd.txt to ingenic,lcd.yaml
and add compatible: jz4780-lcd, including an example how to
configure both lcd controllers.
Also fix the clock names and examples.

-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.
