Input: edt-ft5x06 - increase allowed data range for threshold parameter
The datasheet and application note does not mention an allowed range for
the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set
lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with
T5x06 touch.
So, lacking a known lower limit, we increase the range for thresholds,
and set the lower limit to 0. The documentation is updated accordingly.
