This moves over the configuration of the GPIO keys (used for proximity sensor and Hall effect sensor) from the static pin configuration file to the device tree. As part of the exercise, implement the GPIO keys properly in a per-UIB file as this setup actually differs with each UIB. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
