gpio: Get rid of _prefix and __prefixes
The arbitrarily marking of a function with _ or __ is taking to mean "perform some inner core of the caller" or something like that. At other times, this syntax has a totally different meaning. I don't like this since it is unambious and unhelpful to people reading the code, so replace it with _commit() suffixes. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
