drivers: qdec_sam: disable index signal

Browse source 
`qdec_sam` driver supports currently only position measurement and does
not support reading of the index signal. Unfortunately, the index
signal was internally enabled in the driver. If the pin to which the
index signal was connected was used by another driver it could lead to
a false detection of the signal change. Detection of the index signal
change resets the position measurement.
