Input: psmouse - allow disabing certain protocol extensions

Browse Source 
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.
