dt-bindings: display: sitronix,st7735r: Convert to DT schema



Convert the DT binding documentation for Sitronix ST7735R displays to DT
schema.

Add a reference to the Adafruit 1.8" LCD while at it.

Sitronix ST7735R display panels

This binding is for display panels using a Sitronix ST7735R controller in SPI
mode.

Required properties:
- compatible:	"jianda,jd-t18003-t01", "sitronix,st7735r"
- dc-gpios:	Display data/command selection (D/CX)
- reset-gpios:	Reset signal (RSTX)

The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in ../spi/spi-bus.txt must be specified.

Optional properties:
- rotation:	panel rotation in degrees counter clockwise (0,90,180,270)
- backlight:	phandle of the backlight device attached to the panel

Example:

	backlight: backlight {
		compatible = "gpio-backlight";
		gpios = <&gpio 44 GPIO_ACTIVE_HIGH>;
	};

	...

	display@0{
		compatible = "jianda,jd-t18003-t01", "sitronix,st7735r";
		reg = <0>;
		spi-max-frequency = <32000000>;
		dc-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
		rotation = <270>;
		backlight = &backlight;
	};
