OpenWrt's special gpio-button-hotplug driver is still using exclusively the legacy GPIO Subsystem gpio_ API. While it still does work fine for most devices, upstream linux is starting to convert platform support like that of the APU2/3/4 to the new GPIOD LOOKUP tables that are not supported by it. Hence, this patch replaces the gpio_ calls present in gpio-button-hotplug with gpiod_ equivalent wherever it's possible. This allows the driver to use the gpiod lookup tables and still have a fallback for legacy platform data code that just sets button->gpio set to the real button/switch GPIO. As a bonus: the active_low logic is now being handled by the linux's gpio subsystem too. Another issue that was address is the of_handle leak in the dt parser error path.
