Improve touch device configuration.
Bug: 5064702

This change improves compatibility with standard touch device
drivers.  All existing touch device IDC files will need to
be updated because the input system now assumes that the
touch device drivers implement the multitouch input
protocol correctly and use the appropriate axes.
