[PATCH 2/2] input: synaptics - set min/max for finger width

[chris@cnpbagwell.com]

From: Chris Bagwell <chris@cnpbagwell.com>

Reporting this will allow GUI config apps to correctly scale
width sensitive config values (such as palm detect) to correct range.
Current user apps are detecting kernels min/max=0/0 and making
an assumption that it means 0/16 or 0/15.

Synaptics touchpad interface guides show 4/15 are correct values
but driver forces to 0 when no fingers on touchpad.
