dt-bindings: can: convert microchip,mcp251x.txt to yaml 



Convert binding doc microchip,mcp251x.txt to yaml.
Additional change:
- add ref to spi-peripheral-props.yaml

Fix below warning:
arch/arm64/boot/dts/freescale/imx8dx-colibri-eval-v3.dtb: /bus@5a000000/spi@5a020000/can@0:
	failed to match any schema with compatible: ['microchip,mcp2515']

* Microchip MCP251X stand-alone CAN controller device tree bindings



Required properties:

 - compatible: Should be one of the following:

   - "microchip,mcp2510" for MCP2510.

   - "microchip,mcp2515" for MCP2515.

   - "microchip,mcp25625" for MCP25625.

 - reg: SPI chip select.

 - clocks: The clock feeding the CAN controller.

 - interrupts: Should contain IRQ line for the CAN controller.



Optional properties:

 - vdd-supply: Regulator that powers the CAN controller.

 - xceiver-supply: Regulator that powers the CAN transceiver.

 - gpio-controller: Indicates this device is a GPIO controller.

 - #gpio-cells: Should be two. The first cell is the pin number and

                the second cell is used to specify the gpio polarity.



Example:

	can0: can@1 {

		compatible = "microchip,mcp2515";

		reg = <1>;

		clocks = <&clk24m>;

		interrupt-parent = <&gpio4>;

		interrupts = <13 IRQ_TYPE_LEVEL_LOW>;

		vdd-supply = <&reg5v0>;

		xceiver-supply = <&reg5v0>;

		gpio-controller;

		#gpio-cells = <2>;

	};
