UniPhier reset controller


System reset
------------

Required properties:
- compatible: should be one of the following:
    "socionext,uniphier-sld3-reset" - for PH1-sLD3 SoC.
    "socionext,uniphier-ld4-reset"  - for PH1-LD4 SoC.
    "socionext,uniphier-pro4-reset" - for PH1-Pro4 SoC.
    "socionext,uniphier-sld8-reset" - for PH1-sLD8 SoC.
    "socionext,uniphier-pro5-reset" - for PH1-Pro5 SoC.
    "socionext,uniphier-pxs2-reset" - for ProXstream2/PH1-LD6b SoC.
    "socionext,uniphier-ld11-reset" - for PH1-LD11 SoC.
    "socionext,uniphier-ld20-reset" - for PH1-LD20 SoC.
- #reset-cells: should be 1.

Example:

	sysctrl@61840000 {
		compatible = "socionext,uniphier-ld20-sysctrl",
			     "simple-mfd", "syscon";
		reg = <0x61840000 0x4000>;

		reset {
			compatible = "socionext,uniphier-ld20-reset";
			#reset-cells = <1>;
		};

		other nodes ...
	};


Media I/O (MIO) reset
---------------------

Required properties:
- compatible: should be one of the following:
    "socionext,uniphier-sld3-mio-reset" - for PH1-sLD3 SoC.
    "socionext,uniphier-ld4-mio-reset"  - for PH1-LD4 SoC.
    "socionext,uniphier-pro4-mio-reset" - for PH1-Pro4 SoC.
    "socionext,uniphier-sld8-mio-reset" - for PH1-sLD8 SoC.
    "socionext,uniphier-pro5-mio-reset" - for PH1-Pro5 SoC.
    "socionext,uniphier-pxs2-mio-reset" - for ProXstream2/PH1-LD6b SoC.
    "socionext,uniphier-ld11-mio-reset" - for PH1-LD11 SoC.
    "socionext,uniphier-ld20-mio-reset" - for PH1-LD20 SoC.
- #reset-cells: should be 1.

Example:

	mioctrl@59810000 {
		compatible = "socionext,uniphier-ld20-mioctrl",
			     "simple-mfd", "syscon";
		reg = <0x59810000 0x800>;
