Suppress out of range warning messages

If touchpad firmware does not report correct boundaries of touchpad
surface, the library keeps printing out warning messages in Xorg.0.log
once a finger is on the 'out of range' position. The patch tries to
suppress this kind of messages by updating effective boundary of X/Y
axis once the reported event is out of current range.

BUG=chromium-os:16477
TEST=on device; move a finger around the boundaries of the touchpad
  and see if the warning messages should be suppressed by updating
  X and Y ranges
