Log Message:
synaptics: Make up_down_emulation useful for single-button clickpads

On devices such as the Thinkpad X250, the clickpad can be pressed
to generate mouse button events 1 and 2. There are also additional
physical buttons which the pms(4) driver recognizes as "up/down" buttons
(mouse buttons 3 and 4). Allow these to be remapped to buttons 1 and 2
and used like normal touchpad buttons with the following sysctl:

# sysctl -w hw.synaptics.up_down_emulation=3

While here, adjust the existing "middle button emulation"
(hw.synaptics.up_down_emulation=1) so it works with single-button
clickpads.

XXX: 3 may be a more useful default than the current default,
depending on hardware availability of touchpads with "up/down buttons".

Update the documentation accordingly.
