dt-bindings: clock: Convert moxa,moxart-clock to DT schema

Device Tree Clock bindings for arch-moxart

This binding uses the common clock binding[1].

[1] Documentation/devicetree/bindings/clock/clock-bindings.txt

MOXA ART SoCs allow to determine PLL output and APB frequencies

by reading registers holding multiplier and divisor information.

PLL:

Required properties:

- compatible : Must be "moxa,moxart-pll-clock"

- #clock-cells : Should be 0

- reg : Should contain registers location and length

- clocks : Should contain phandle + clock-specifier for the parent clock

Optional properties:

- clock-output-names : Should contain clock name

APB:

Required properties:

- compatible : Must be "moxa,moxart-apb-clock"

- #clock-cells : Should be 0

- reg : Should contain registers location and length

- clocks : Should contain phandle + clock-specifier for the parent clock

Optional properties:

- clock-output-names : Should contain clock name

For example:

	clk_pll: clk_pll@98100000 {

		compatible = "moxa,moxart-pll-clock";

		#clock-cells = <0>;

		reg = <0x98100000 0x34>;

	};

	clk_apb: clk_apb@98100000 {

		compatible = "moxa,moxart-apb-clock";

		#clock-cells = <0>;

		reg = <0x98100000 0x34>;

		clocks = <&clk_pll>;

	};
