I2C_OWN_SLAVE_ADDRESS definately not. ATR is only for addresses on the
remote bus while our own address is on the local bus.

I2C_TEN_BIT_ADDRESS, only in theory. I have never seen a 10-bit address
in the wild, so extremely unlikely that ATR hardware does support it.

But then again, there is a slight chance that we add more flags in the
future which might be relevant for ATR? So, u32 is probably a good
thing to use nonetheless.
