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
regulators: anatop: add set_voltage_time_sel interface some of anatop's regulators(cpu, vddpu and vddsoc) have register settings about LDO's step time, which will impact the LDO ramp up speed, need to use set_voltage_time_sel interface to add necessary delay everytime LDOs' voltage is increased. offset 0x170: bit [24-25]: cpu bit [26-27]: vddpu bit [28-29]: vddsoc field definition: 0'b00: 64 cycles of 24M clock; 0'b01: 128 cycles of 24M clock; 0'b02: 256 cycles of 24M clock; 0'b03: 512 cycles of 24M clock; Signed-off-by: Anson Huang <b20788@freescale.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Optional properties:
- anatop-delay-reg-offset: Anatop MFD step time register offset
- anatop-delay-bit-shift: Bit shift for the step time register

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

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>;
