Convert each file at I2C subsystem, renaming them to .rst and
adding to the driver-api book.

i2c: i2c-mux-gpio: rename i2c-gpio-mux to i2c-mux-gpio2017-02-09T16:01:47+00:00Peter Rosinpeda@axentia.se2017-02-07T21:41:55+00:00urn:sha1:6b66a6f27e799d9441ef2c0b1e00913a6a070fa5
The rename did the wrong thing for this documentation file all those
years ago. Fix that as well as the neglected rename of the platform
data structure.

* Document the possibility to pass relative GPIO pin numbers.
* Document what platform device IDs to use, so that they do not
collide.

i2c: Add generic I2C multiplexer using GPIO API2011-01-10T21:11:23+00:00Peter Korsgaardpeter.korsgaard@barco.com2011-01-10T21:11:23+00:00urn:sha1:92ed1a76ca31774eb27de14b2215841367c68056
Add an i2c mux driver providing access to i2c bus segments using a
hardware MUX sitting on a master bus and controlled through gpio pins.
E.G. something like:
---------- ---------- Bus segment 1 - - - - -
| | SCL/SDA | |-------------- | |
| |------------| |
| | | | Bus segment 2 | |
| Linux | GPIO 1..N | MUX |--------------- Devices
| |------------| | | |
| | | | Bus segment M
| | | |---------------| |
---------- ---------- - - - - -
SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M
according to the settings of the GPIO pins 1..N.
