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.
