dt-bindings: serial: brcm,bcm6345-uart: convert to the json-schema 



This helps validating DTS files.

Redundant generic descriptions (e.g. "The base address of the UART
register bank") were dropped and periph_clk was dropped from example as
not required.

* BCM63xx UART



Required properties:



- compatible: "brcm,bcm6345-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.





Optional properties:



- clock-names: Should be "refclk".



Example:



	uart0: serial@14e00520 {

		compatible = "brcm,bcm6345-uart";

		reg = <0x14e00520 0x18>;

		interrupt-parent = <&periph_intc>;

		interrupts = <2>;

		clocks = <&periph_clk>;

		clock-names = "refclk";

	};



	clocks {

		periph_clk: periph_clk@0 {

			compatible = "fixed-clock";

			#clock-cells = <0>;

			clock-frequency = <54000000>;

		};

	};
