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>;
