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>;
+ };
