ARM: ux500: fix up the I2C devices
The I2C device registration on the different ux500 board was buggy due to a switch to dynamically assigned I2C host addresses. This I2C host is still there, but we have to add the devices dynamically instead of using board data. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
