rambi: change EC accel sampling rate and default sensor output data rate.
Two accelerometer changes:
- Lower accel sampling rate when chipset is off to 10Hz. Increase
sampling rate back up to 100Hz when transitioning to S0.
- Change the default output data rate of the accelerometers to 100Hz
which matches the EC sampling rate when in S0.
BUG=none
BRANCH=rambi
TEST=manual testing. used lidangle command to verify that in S0,
EC is sampling at 100Hz, and in S3 or lower it is sampling at 10Hz.
