iio: kx022a: Support ROHM KX132ACR-LBZ

Browse Source 
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.
