iio: accel: kx022a: Support ICs with different G-ranges

The register interface of the ROHM KX134ACR-LBZ accelerometer is almost
identical to the KX132ACR-LBZ. Main difference between these
accelerometers is that the KX134ACR-LBZ supports G-ranges +/- 8, 16,
32 and 64G. All the other sensors supported by the kx022a driver can
measure +/- 2, 4, 8 and 16G.

Prepare supporting the KX134ACR-LBZ with different G-ranges by storing
a pointer to the scale tables in IC specific structure.
