I thought about this, too, but decided against it. Maybe some driver
doesn't want to make its slave interface public because it is
specialized for one use-case only (thinking ECs here)? Also, doing it
would be a little inconsistent, since we could do the same for
I2C_FUNC_I2C when master_xfer is populated. So, let's start simple I'd
say.
