Input: zaurus keyboard driver updates 

  * Change the scan interval from 100ms to 50ms. This stops the key
    repeat from triggering on double letter presses.
  * Remove unneeded stale hinge code from corgikbd
  * Change unneeded corgi GPIO pins to inputs when suspended
  * Add support for the headphone jack switch for both corgi and spitz
    (as switch SW_2)
