xenfb: activate input handlers for raw pointer devices

If the frontend requests raw pointers, the input handlers must be activated to have the input events delivered to the xenfb backend. Without activation, the input events are delivered to handlers registered earlier, which would be the emulated USB tablet or emulated PS/2 mouse. HVM xen_kbdfront can incorrectly scale absolute coordinates when the display resolution is not 800x600.
