Hi,

This patch make sure that the timestamp element is the last element
in the iio_chan_spec.
The index values for the timestamp was hardcoded and 
in conflict with other elements (at least on adis16448).

This is a problem in iio_compute_scan_bytes(). The function is 
searching for the first element with the timestamp index.
If the found element has a lesser number of storage bits, this
is a potential buffer overflow issue.
