common: sensors: add extra sensor attributes
Adds min_frequency and max_frequency to struct motion_sensor_t.
New attributes min_frequency and max_frequency are now returned in
ectool's MOTIONSENSE_CMD_INFO response.
Incremented ectool's MOTIONSENSE_CMD_INFO version to version 3.
Add constants for MIN_FREQUENCY and MAX_FREQUENCY to each sensor's
header file.
BRANCH=none
BUG=chromium:615059
TEST=build/boot and verify MOTIONSENSE_CMD_INFO response on kevin,
make buildall -j passes.
