Input: add Raydium I2C touchscreen driver

Raydium I2C touchscreen

Required properties:

- compatible: must be "raydium,rm32380"

- reg: The I2C address of the device

- interrupt-parent: the phandle for the interrupt controller

- interrupts: interrupt to which the chip is connected

    See ../interrupt-controller/interrupts.txt

Optional properties:

- avdd-supply: analog power supply needed to power device

- vccio-supply: IO Power source

- reset-gpios: reset gpio the chip is connected to.

Example:

	touchscreen@39 {

		compatible = "raydium,rm32380";

		reg = <0x39>;

		interrupt-parent = <&gpio>;

		interrupts = <0x0 IRQ_TYPE_EDGE_FALLING>;

	};
