dt-bindings: iio: Add KX132ACR-LBZ accelerometer ROHM KX132ACR-LBZ is an accelerometer for industrial applications. It has a subset of KX022A functionalities, dropping support for tap, free fall and tilt detection engines. Also, the register interface is an exact subset of what is found on KX022A (except the WHO_AM_I register value). Add support for KX132ACR-LBZ.
