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)
