MFD_DA9062 is a bool symbol. So da9062-core.o can never be part of a
module, right?

So you might not need this include.

This macro will be preprocessed away for built-in code, according to
include/linux/module.h.

Ditto.

After looking at a few levels of #defines I think this is equivalent to
i2c_register_driver(NULL, da9062_i2c_driver);
for built-in code. Did I grep that right?

These macros will be effectively preprocessed away for built-in only
code.
