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

Previously our accel / gyro drivers assumed that we had exactly two of
each identical part in the system. Some systems may have different
configurations, so allow this to be specified at the board-level.
Note that our motion_sense algorithm currently assumes that we have one
accelerometer in the lid and one in the base -- we'll need to fix that
in another CL.

Created a host command to set/get various motion sensor parameters and
added an ectool command to use that host command.
The host command is created such that the first argument is a
sub-command. Sub-commands created include:
dump: dumps all current motion sensor data
info: returns general information about each motion sensor
ec_rate: set/get the EC sampling rate of sensors
sensor_range: set/get the sensor range (ie +/- 2G,4G,8G)
sensor_odr: set/get the sensor output data rate (ie 50Hz, 100Hz, ...)
For sensor_range and sensor_odr parameters, since the host doesn't know
what are valid values for the parameter, the host can specify to round
up or down to the nearest valid value. For example, the host can specify
to set the output data rate to at least 100Hz, and the EC will return
the closest valid output data rate that is at least 100Hz.

TEST=Test on a glimmer using ectool from vt-2 prompt:
> ectool motionsense help
Usage:
motionsense - dump all motion data
motionsense info NUM - print sensor info
motionsense ec_rate [RATE_MS] - set/get sample rate
motionsense odr NUM [ODR [ROUNDUP]] - set/get sensor ODR
motionsense range NUM [RANGE [ROUNDUP]]- set/get sensor range

After running this I verified on the EC console that all the parameters
were set appropriately. I tested the EC sampling rate was 1000ms by
running lidangle on and making sure samples were displayed roughly every
second. I verified the sensor odr and range by defining
CONFIG_CMD_ACCELS and typing:
> accelrange 0
8
> accelrate 0
50000
