iio: imu: fxos8700: fix ACCEL measurement range selection

commit 9d61c1820598a5ea474576ed55318a6dadee37ed upstream.

When device is in active mode, it fails to set an ACCEL full-scale
range(2g/4g/8g) in FXOS8700_XYZ_DATA_CFG. This is not align with the
datasheet, but it is a fxos8700 chip behavior.

Keep the device in standby mode before setting ACCEL full-scale range
into FXOS8700_XYZ_DATA_CFG in chip initialization phase and setting
scale phase.
