Binding for TZ1090 clock deleter.

This binding uses the common clock binding[1]. The TZ1090 clock deleters can be
configured to delete a certain fraction of the input clock pulses. For a
configuration field of "width" bits with the value "delete_cycles",
delete_cycles cycles are deleted out of every 1 << width cycles, so the output
frequency is:

    f_out = f_in * ((1 << width) - config) / (1 << width)

Required properties:
- compatible         : Shall be "img,tz1090-deleter".
- #clock-cells       : From common clock binding; shall be set to 0.
- reg                : Address of configuration register.
- shift              : Shift of config value field in configuration register.
- width              : Width of config value field in configuration register.
- clocks             : From common clock binding.

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

Optional properties:
- clock-output-names : From common clock binding.

Example:
	meta_clkdelete {
		compatible = "img,tz1090-deleter";
		#clock-cells = <0>;
		clocks = <&sys_clk_x2_undeleted>;
		reg = <0x0200591c 0x4>;	/* CR_TOP_META_CLKDELETE */
		shift = <0>;		/* CR_TOP_META_CLKDELETE */
		width = <12>;
		clock-output-names = "meta";
	};
