It seems to me this file slips into your patch, but it was not supposed
to be.

The pmic_ prototypes have nothing to do with the Soc prototype, as they
are specific for a driver. You should move them in the dialog header.

Probably it does not make a lot of sense to build this board without I2C
support. If this is the case, you should drop the #ifdef, as your board
must always be compiled with I2C.
