iio: core: Introduce DISTANCE channel type
Some devices export an estimation of the distance the user has covered
since the last reset.
One of this devices is Freescale's MMA9553L
(http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf)
that computes the distance based on the stride length and step rate.
Introduce a new channel type DISTANCE to export these values.
