Andres Salomon 55e3d9224b Input: psmouse - allow disabing certain protocol extensions
Allow ALPS, LOGIPS2PP, LIFEBOOK, TRACKPOINT and TOUCHKIT protocol
extensions of psmouse to be disabled during compilation. This will
allow users save some memory when they are sure that they will only
use a certain type of mice.
