drivers/sensor: add support to IIS2ICLX accelerometer

The IIS2ICLX is a high-accuracy. ultra-low noise, low-power
two-axis linear accelerometer which can be interfaced through
either I2C or SPI bus.
Its high accuracy, stability over temperature and repeatability
make IIS2ICLX particularly suitable for inclination measurement
for industrial applications (inclinometers).
