Convert the Broadcom BCM2835 Auxiliar 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.
