iio: Add IIO_DELTA_VELOCITY channel type
The delta velocity is defined as a piece-wise integration of
acceleration data. The delta velocity represents the linear velocity
change between two consecutive measurements and it
is measured in m / s (meters per second).
In order to track the total linear velocity change during a desired
period of time, simply sum-up the delta velocity samples acquired
during that time.
IIO currently does not offer a suitable channel type for this
type of measurements hence this patch adds it.
