SensorService now always clamps the requested rate
Requested rate will be clamped to the minimum rate and then
to 1ms. Previously we would return an error if a lower
rate was asked. The SensorManager documentation wording
allows this change.
We do this to get more consistancy between all the sensor
drivers / HALs
