i2c: i2c-mux-gpio: rename i2c-gpio-mux to i2c-mux-gpio

Browse source 
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.

If you don't know the absolute GPIO pin numbers at registration time,
you can instead provide a chip name (.chip_name) and relative GPIO pin
numbers, and the i2c-gpio-mux driver will do the work for you,

Device Registration

When registering your i2c-mux-gpio device, you should pass the number
of any GPIO pin it uses as the device ID. This guarantees that every
instance has a different ID.
