Add support to STM ASM330LHHX (acc + gyro) automotive Mems sensor.
The ASM330LHHX sensor can use LSM6DSR as fallback device since it
implements all the ASM330LHHX features currently implemented in
st_lsm6dsx.

Add device bindings for asm330lhhx IMU sensor.
Use lsm6dsr as fallback device for asm330lhhx since it implements all
the features currently supported by asm330lhhx.
