Changed motion_sense task to assume sensors are unpowered in G3 and re-initialize sensors every time coming out of G3. Added EC command line test utils as well. Fixed some bug during unit tests. BUG=chrome-os-partner:27313,27320 BRANCH=ToT TEST=Verified on Samus. Tested with accel EC CLIs accelread, accelrange, accelrate, accelres Tested accelcalib, a ACCEL calibration util, and it succeeded. Tested sysfs interface: cd /sys/bus/iio/devices/iio:device1 cat in_accel_*_gyro_raw Signed-off-by: Sheng-Liang Song <ssl@chromium.org> Change-Id: I5752b00c03e1942c790ea4f28610fda83fa2dcbc Reviewed-on: https://chromium-review.googlesource.com/211484 Reviewed-by: Alec Berg <alecaberg@chromium.org>
