Well, it seems that the issue the PRP0001 people are having is that
they'd rather that there were fewer OF only drivers!  More generally
it is good practice to write things as though there might be non-DT
support even if it's not there at the present time, it's easier to not
have to think if it's strictly needed and it helps anyone coming along
later who does want to use things elsewhere.
