spitz: add gpio button support

[Pavel Machek]

This is call for testing/comments. It adds support for power button,
SWA and SWB.. I'm not sure what AK_INT is, nor what event it should
generate. Unfortunately, this does _not_ fix suspend/resume, and
neither does switch back to old spitz-keyboard help.
