docs: w1: convert to ReST and add to the kAPI group of docs

The 1wire documentation was written with w1 developers in
mind, so, it makes sense to add it together with the driver-api
set.

-Description
------------
-
-The DS2438 chip provides several functions that are desirable to carry in
-a battery pack. It also has a 40 bytes of nonvolatile EEPROM.
-Because the ability of temperature, current and voltage measurement, the chip
-is also often used in weather stations and applications such as: rain gauge,
-wind speed/direction measuring, humidity sensing, etc.
-
-Current support is provided through the following sysfs files (all files
-except "iad" are readonly):
-
-"iad"
------
-This file controls the 'Current A/D Control Bit' (IAD) in the
-Status/Configuration Register.
-Writing a zero value will clear the IAD bit and disables the current
-measurements.
-Writing value "1" is setting the IAD bit (enables the measurements).
-The IAD bit is enabled by default in the DS2438.
-
-When writing to sysfs file bits 2-7 are ignored, so it's safe to write ASCII.
-An I/O error is returned when there is a problem setting the new value.
-
-"page0"
--------
-This file provides full 8 bytes of the chip Page 0 (00h).
-This page contains the most frequently accessed information of the DS2438.
-Internally when this file is read, the additional CRC byte is also obtained
-from the slave device. If it is correct, the 8 bytes page data are passed
-to userspace, otherwise an I/O error is returned.
-
-"temperature"
--------------
-Opening and reading this file initiates the CONVERT_T (temperature conversion)
-command of the chip, afterwards the temperature is read from the device
-registers and provided as an ASCII decimal value.
-
-Important: The returned value has to be divided by 256 to get a real
-temperature in degrees Celsius.
-
-"vad", "vdd"
-------------
-Opening and reading this file initiates the CONVERT_V (voltage conversion)
-command of the chip.
-
-Depending on a sysfs filename a different input for the A/D will be selected:
-vad: general purpose A/D input (VAD)
-vdd: battery input (VDD)
-
-After the voltage conversion the value is returned as decimal ASCII.
-Note: To get a volts the value has to be divided by 100.
