pwm regulator bindings

Required properties:
- compatible: Should be "pwm-regulator"
- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
- voltage-table: voltage and duty table, include 2 members in each set of
  brackets, first one is voltage(unit: uv), the next is duty(unit: percent)

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

Example:
	pwm_regulator {
		compatible = "pwm-regulator;
		pwms = <&pwm1 0 8448 0>;

		voltage-table = <1114000 0>,
				<1095000 10>,
				<1076000 20>,
				<1056000 30>,
				<1036000 40>,
				<1016000 50>;

		regulator-min-microvolt = <1016000>;
		regulator-max-microvolt = <1114000>;
		regulator-name = "vdd_logic";
	};
