It is fine for now, but attach_dev really should be a function that
just does identity and what is left should really just only do
paging. Same for blocked. That simplifies the flows quite a bit..

It would also be really nice if the identity_domain and blocked_domain
was not a struct protection_domain like all the other drivers have
managed..
