So much mess, as people defines 1.8V i2c level shifters instead of VDD.

I don't pocess any of these devices, so please test carefully,
you may need to in addition to this change put regulator-always-on to
the 1.8V which was previously abused instead of VDD. Careful about
combination when camera which pulls in 1.8V (usually iovdd) as a byproduct
takes care of i2c supply for the coil.
