Mma8x5x accelerometer driver continue polling sensor data after
sensor power off, this is because power state flag has been added
into sensor state variable but control condition logic did not
update accordingly.

Force firmware update cannot work when touchscreen controller
cannot report correct family ID. If touchscreen is does not work
in correct state and it reports wrong family ID, it cannot be
recovered by force update, this change use family ID from device
tree instead of read from controller register to fix this issue.
