This seems to be heading in the wrong direction though.

The IF_TYPE should really go away and be replaced with the UCLASS ID, I think.

At present we have lots of calls to blk_create_device_f() which
specify the type. I think we should drop the IF_TYPE_.. arg to that
function and have it figured out from the uclass, in the interim.

But why do we need IF_TYPE now?

Simon
