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)
