Binding for generic integer clock divider.

This binding uses the common clock binding[1].

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

Required properties:
- compatible         : Shall be "divider-clock".
- #clock-cells       : From common clock binding; shall be set to 0.
- reg                : Address of divider register.
- shift              : Shift of field in divider register.
- width              : Width of field in divider register.
- clocks             : From common clock binding.

Required source clocks:
- 0                  : Reference clock which is divided to produce the output
                       clock (doesn't have to be named).

Optional properties:
- one-based          : Indicates that register field stores the divisor directly
                       rather than the default of divisor-1.
- power-of-two       : Indicates that register field stores log2(divisor) rather
                       that the default of divisor-1.
- clock-output-names : From common clock binding.
- linux,clk-read-only: Flag to indicate that the divide shouldn't be altered.
- default-divide     : Default divider value.

Example:
	clock {
		compatible = "divider-clock";
		#clock-cells = <0>;
		clocks = <&sys_pll>;
		reg = <0x02005914 0x4>;	/* CR_TOP_SYSCLK_DIV */
		shift = <0>;		/* CR_TOP_SYSDIV */
		width = <8>;
		clock-output-names = "sysclk_div";
	};
