regulator: anatop: patching to device-tree property "reg". 



Change "reg" to "anatop-reg-offset" due to there is a warning of handling no
size field in reg.

This patch also adds the missing device-tree binding documentation.

Anatop Voltage regulators



Required properties:

- compatible: Must be "fsl,anatop-regulator"

- anatop-reg-offset: Anatop MFD register offset

- anatop-vol-bit-shift: Bit shift for the register

- anatop-vol-bit-width: Number of bits used in the register

- anatop-min-bit-val: Minimum value of this register

- anatop-min-voltage: Minimum voltage of this regulator

- anatop-max-voltage: Maximum voltage of this regulator



Any property defined as part of the core regulator

binding, defined in regulator.txt, can also be used.



Example:



	regulator-vddpu {

		compatible = "fsl,anatop-regulator";

		regulator-name = "vddpu";

		regulator-min-microvolt = <725000>;

		regulator-max-microvolt = <1300000>;

		regulator-always-on;

		anatop-reg-offset = <0x140>;

		anatop-vol-bit-shift = <9>;

		anatop-vol-bit-width = <5>;

		anatop-min-bit-val = <1>;

		anatop-min-voltage = <725000>;

		anatop-max-voltage = <1300000>;

	};
