Input: synaptics - only report width on hardware that supports it
Synaptics devices report fixed value of 5 for finger/palm widths on devices that do not support capability and driver further hardcodes to 5. Stop reporting this fixed value when its not supported since its not useful. This will aid applications so they can better auto-enable support for multi-touch emulation and palm detection logic using finger width only for devices that support width detection. I can find no applications that currently require existence on ABS_TOOL_WIDTH. Since only synaptics and bcm input devices currently support this tool, it seems they must handle it gracefully.
