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;
};
