Input: atmel_mxt_ts - set byte_offset as signed

Browse Source 
The calculations done to obtain byte_offset can result into a negative
number, fix its type.

This patch fixes the following sparse error:

drivers/input/touchscreen/atmel_mxt_ts.c:1481:44: warning: unsigned value that used to be signed checked against zero?
drivers/input/touchscreen/atmel_mxt_ts.c:1479:49: signed value source
