TPS6586x family of regulators

Required properties:
- compatible: "ti,tps6586x"
- reg: I2C slave address
- interrupts: the interrupt outputs of the controller
- #gpio-cells: number of cells to describe a GPIO
- gpio-controller: mark the device as a GPIO controller
- regulators: A node that houses a sub-node for each regulator within the
  device. Each sub-node is identified using the node's name (or the deprecated
  regulator-compatible property if present), with valid values listed below.
  The content of each sub-node is defined by the standard binding for
  regulators; see regulator.txt.
  sys, sm[0-2], ldo[0-9] and ldo_rtc
- sys-supply: The input supply for SYS.
- vin-sm0-supply: The input supply for the SM0.
- vin-sm1-supply: The input supply for the SM1.
- vin-sm2-supply: The input supply for the SM2.
- vinldo01-supply: The input supply for the LDO1 and LDO2
- vinldo23-supply: The input supply for the LDO2 and LDO3
- vinldo4-supply: The input supply for the LDO4
- vinldo678-supply: The input supply for the LDO6, LDO7 and LDO8
- vinldo9-supply: The input supply for the LDO9

Optional properties:
- ti,system-power-controller: Telling whether or not this pmic is controlling
  the system power.

Each regulator is defined using the standard binding for regulators.

Note: LDO5 and LDO_RTC is supplied by SYS regulator internally and driver
      take care of making proper parent child relationship.

Example:

	pmu: tps6586x@34 {
		compatible = "ti,tps6586x";
		reg = <0x34>;
		interrupts = <0 88 0x4>;

		#gpio-cells = <2>;
		gpio-controller;

		ti,system-power-controller;

		sys-supply = <&some_reg>;
		vin-sm0-supply = <&some_reg>;
		vin-sm1-supply = <&some_reg>;
		vin-sm2-supply = <&some_reg>;
		vinldo01-supply = <...>;
		vinldo23-supply = <...>;
		vinldo4-supply = <...>;
		vinldo678-supply = <...>;
		vinldo9-supply = <...>;

		regulators {
			sys_reg: sys {
				regulator-name = "vdd_sys";
				regulator-boot-on;
				regulator-always-on;
			};

			sm0_reg: sm0 {
				regulator-min-microvolt = < 725000>;
				regulator-max-microvolt = <1500000>;
				regulator-boot-on;
				regulator-always-on;
			};

			sm1_reg: sm1 {
