Binding for TZ1090 High end peripheral clocks.

This binding uses the common clock binding[1]. It represents the clocks
controlled from the high end peripheral registers of the TZ1090:

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

Required properties:
- compatible         : Shall be "img,tz1090-hep-cr", "syscon".
- #clock-cells       : From common clock binding; shall be set to 1.
- reg                : Base address for clock registers in high end peripheral
                       register region.
- clocks             : Clock specifiers for each input clock.
- clock-names        : Labels for each input clock specified in clocks.
                       Can contain the following entries:
                       "sys"              : Main system clock.
                       "sys_x2_undeleted" : System clock before division and
                                            deletion.

Optional properties:
- clock-indices      : From common clock binding. Allows clock-output-names to
                       be sparse.
- clock-output-names : From common clock binding. May be used to name specific
                       output clocks so that other clock providers can find
                       the clocks by name before the provider has been
                       instantiated. Can contain:
                       "sys_2d", "ddr_en", "sys_pdp"

Clock Specifier Definition:
- <1st-cell>: Output clock number. Use constants from
              <dt-bindings/clock/tz1090-hep.h>.

Examples:
	hep_cr: hep_cr {
		compatible = "img,tz1090-hep-cr", "syscon";
		#clock-cells = <1>;
		reg = <0x02008c00 0x08>;
		/* input clocks */
		clocks = <&top_clks CLK_TOP_SYS>,
			 <&top_clks CLK_TOP_SYS_X2_UNDELETED>;
		clock-names = "sys",
			      "sys_x2_undeleted";
		/* output clocks for other clock providers */
		clock-indices = <CLK_HEP_DDR_EN>;
		clock-output-names = "ddr_en";
	};

	pdp {
		...
		clocks = <&hep_cr CLK_HEP_PDP>;
		clock-names = "pdp";
		...
	};
