dt-bindings: extcon: convert extcon-usb-gpio.txt to yaml format 

Convert binding doc extcon-usb-gpio.txt to yaml format to fix below
warning:
arch/arm64/boot/dts/freescale/imx8mp-msc-sm2s-ep1.dtb: /extcon-usb0:
    failed to match any schema with compatible: ['linux,extcon-usb-gpio']

Additional change:
- rename id-gpio to id-gpios
- rename vbus-gpio to vbus-gpios

USB GPIO Extcon device



This is a virtual device used to generate USB cable states from the USB ID pin

connected to a GPIO pin.



Required properties:

- compatible: Should be "linux,extcon-usb-gpio"



Either one of id-gpio or vbus-gpio must be present. Both can be present as well.

- id-gpio: gpio for USB ID pin. See gpio binding.

- vbus-gpio: gpio for USB VBUS pin.



Example: Examples of extcon-usb-gpio node in dra7-evm.dts as listed below:

	extcon_usb1 {

		compatible = "linux,extcon-usb-gpio";

		id-gpio = <&gpio6 1 GPIO_ACTIVE_HIGH>;

	}



	&omap_dwc3_1 {

		extcon = <&extcon_usb1>;

	};
