motion_sense: Add more complex EC/AP sensor rate support.

Browse Source 
Add config settings for ODR and EC rate per requestor and
per power state (1 for the AP, 3 for the EC).
This way we can finely set ec rate and ODR depending on usage.

On chromeos, AP is not setting frequency, so EC sets for different power
state. On some platform, sensors can now be suspended in S3/S5.

Allow EC oversampling when AP is only looking for a few samples.
It is useful for double tap detection where high accelerator ODR is
required.
