[PATCH 2/2] i2c-mux-gpio: Rename platform data structure

[Jean Delvare <khali-PUYAD+kWke1g9hUCZPvPmw@public.gmane.org>]

Align the name of i2c-mux-gpio's data structure on the new driver name.
Also change one define and adjust function names, even if they aren't
part of the public interface, for consistency.

I made this a separate patch for easier testing/review/bisection.
Wolfram, feel free to merge into the first patch if you prefer a
single patch.
