input: Change AT keyboard to use hardware autorepeat and move

       untranslating to the AT keyboard driver as well. Lower
       PS/2 mouse default report rate. Fix repeat rate adjustment
       ioctls accordingly, and update other files to reflect the
       changes. This should fix most known keyboard problems in 2.6.
