a given target, the runtime registration stuff adds some overhead and
perhaps we could build the callback table at compile time (using some
ifdefs). Something like perhaps:

static const struct i2c_struct *i2c_if[MAX_I2C_INTERFACES] =

{
#ifdef MY_I2C_FOR_MY_TARGET
  [MY_I2C_IFACE_NR] = ...
#endif
....
};
