Some BH1750 sensors require a hardware reset via GPIO before they can
be properly detected on the I2C bus. Add a new reset-gpios property
to the binding to support this functionality.
The reset-gpios property allows specifying a GPIO that will be toggled
during driver initialization to reset the sensor.
