Subject: [PATCH v4 4/4] input: synaptics - make image sensors and cr48 sensors report widths

Despite claiming to report finger widths, image sensors and cr48
profile sensors were not doing it. Since the touchpad uses an
abstract unit for the width of the fingers, report only the witdh
of the first touch using ABS_TOOL_WIDTH.
