This is an untested WIP but as it was coming in discussion about device-tree
as well I figured it will be useful to post the prototype code at this point.
There is lots left to do - in particular resource claim/release should be an
ops method, and it's going to need people to update various embedded 8250
drivers when we finally go for a version of it.
On the bright side once we have an ops structure we have the basis for avoiding
further mayhem in the arch code.
