Input: elantech - remove ETP_EDGE_FUZZ_V2 

Don't try to be too clever and remove ETP_EDGE_FUZZ_V2. X, Y ranges
should be just the raw resolution of the device. Otherwise, they can
cause underflow on the Y axis.

* It seems the resolution for hardware version 2 doubled.
* Hence the X and Y ranges are doubled too.
* The bezel around the pad also appears to be smaller
* The resolution for older v2 hardware doubled.
* (newer v2's firmware provides command so we can query)
