Generally the above looks ok and should work like this. Try 'devinfo'
command and identify the gpio-keys device (usually named gpio-keys.<x>).
Use 'devinfo gpio-keys.<x>' to find out if there is a driver attached to
this device. If there isn't, do you find something about gpio-keys in
the boot log?
