motion: Add sample frequency per sensor

Store at which frequency each sensor should be sampled.
This frequency is different from the sensor frequency:
- sensor frequency: frequency at which the sensor produce information.
- sensor sampling frequency: frequency at the which the EC gater
information.
If 2 sensors must be sampled at very different frequency,
we don't want to oversample the slow one, and filling the
software FIFO unnecessarily.

BRANCH=smaug
TEST=Unit test. Check that frequency is correct when sensor
frequencies change from IIO driver.
