BCM Fixed regulator(s)

Required properties:
- compatible: Must be "regulator-bcm-fixed";

At least one property needs to be defined:
- power-gpios: gpio to use to enable/disable power control
- reset-gpios: gpio to use to assert/deassert reset line
The state of these GPIOs on boot up will be set similar to the state when
regulator is disabled.

Optional properties:
- startup-delay-us: delay in microseconds after enabling power-gpios
- shutdown-delay-us: delay in microseconds after disabling power-gpios
- assert-delay-us: delay in microseconds after enabling reset-gpios
- deassert-delay-us: delay in microseconds after disabling reset-gpios
- pinctrl-names: pinctrl state names

If pinctrl-names is defined then it should have off and on states defined
- pinctrl-0: corresponds to disabled pin states
- pinctrl-1: corresponds to enabled pin states

Any property defined as part of the core regulator
binding, defined in regulator.txt, can also be used.

Example:

	abc: bcm-fixed-regulator@0 {
		compatible = "regulator-bcm-fixed";
		regulator-name = "bcm-fixed-regulator";
		power-gpios = <&pinctrl_gpio 129 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&pinctrl_gpio 43 GPIO_ACTIVE_LOW>;
		pinctrl-names = "off", "on";
		pinctrl-0 = <&state_off>;
		pinctrl-1 = <&state_on>;
		startup-delay-us = <200000>;
		assert-delay-us = <200000>;
		deassert-delay-us = <200000>;
	};
