Only problem I would have is if it is breaking other boards in the
mean time until all clocking and pinmux stuff is supported... but like
I said before (in your [1]), if a person finds they need this when
porting an eth driver to DM and they don't have the needed other DM
driver yet, this can easily be reverted when that situation comes up.
