This adds a gpio-driver which multiplexes existing GPIOs using latches. Uwe asked [1] if that would be accectable as a new gpio driver, and here is the result. For a better description what this is all about have a look at the drawings in the patches.

Changes since v1: - Use gpiod_set_value_cansleep when the underlying GPIOs might sleep - Move MODULE_DEVICE_TABLE near to the end - Add license to binding file - remove trailing whitespaces
