ARM: ux500: Remove traces of the ios_handler from platform code
Now MMCI on/off functionality is using the regulator framework from the MMCI driver, there is no need to keep the ios_handler laying around, duplicating functionality. So we're removing it. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
