Adaptive Suspend: configure first param set

This CL configures the first set of experimental parameters for Adaptive
Suspend on targeted devices, including:
* dropping the max backoff from default 60 seconds down to 40
* changing the break-even threshold from 5 seconds (which was just for
  collecting data) to 2
* enabling backoff on short suspends
