Subject: Implement a workaround for Elantech touchpads

All Elantech touchpads report the number of fingers explicitly,
and at least the v3 version of the hardware can report any
pressure values down to zero. This interferes with the tap
detection hysteresis, which is required for dumb touchpads.

This commit implements a vendor-specific workaround for Elantech
touchpads which sets the FingerLow and FingerHigh options to 1
by default, effectively disabling the hysteresis mechanism.
