Input: synaptics - initialize pointer emulation usage 



To properly setup event parameters for emulated events, pass
the appropriate flag to the slot initialization function. Also,
all MT-related events should be setup before initialization.

Incidentally, this solves the issue of doubly filtered pointer
events.
