dt-bindings: serial: brcm,bcm2835-aux-uart: convert to dtschema 



Convert the Broadcom BCM2835 Auxiliary UART to newer DT schema.
Created DT schema based on the .txt file which had
`compatible`, `reg` `clocks` and `interrupts` as the
required properties. This binding is used by Broadcom BCM2835
SOC used in some Raspberry PI boards.
Changes from original file:
Implemented complete example which the original txt binding lacked.

* BCM2835 AUXILIAR UART



Required properties:



- compatible: "brcm,bcm2835-aux-uart"

- reg: The base address of the UART register bank.

- interrupts: A single interrupt specifier.

- clocks: Clock driving the hardware; used to figure out the baud rate

  divisor.



Example:



	uart1: serial@7e215040 {

		compatible = "brcm,bcm2835-aux-uart";

		reg = <0x7e215040 0x40>;

		interrupts = <1 29>;

		clocks = <&aux BCM2835_AUX_CLOCK_UART>;

	};
