... and then we need to create our own sub object model around the 
UCLASS_EFI devices again. I' not convinced that's a great idea yet :). I 
really see little reason not to just expose every dm device as EFI 
handle. Things would plug in quite naturally I think.

But either way, someone would need to sit down and prototype things to 
be sure.
