Convert GPIO-connected buttons and LEDs in Geode boards to software nodes/properties, so that support for platform data can be removed from gpio-keys driver (which will rely purely on generic device properties for configuration). To avoid repeating the same data structures over and over and over factor them out into a new geode-common.c file.
