Dmitry Torokhov 298c9babad x86/platform/geode: switch GPIO buttons and LEDs to software properties
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.
