All these options are SDIO, right?

We had someone from the community asking about that earlier and it 
looked trivial to add it. I will get back on this.

The BT part is done by another group within broadcom so I have no idea 
about their plans. I suspect they can be supported by generic btsdio 
driver, but I may be totally mistaken.
