accel: added mutex to protect critical code in kxcj9 accel driver
Added a mutex in kxcj9 accelerometer driver to prevent concurrent
accesses when writing to critical registers on sensor.
Also added more console debugging functions behind CONFIG_CMD_ACCELS
to allow writing a new range, resolution, or data rate to each
sensor.
BUG=chrome-os-partner:26884
BRANCH=rambi
TEST=Tested by defining CONFIG_CMD_ACCELS and playing around with
writing/reading various parameters on each sensor and making sure
that the accelerometer is still reporting data every so often using
the lidangle on command.
