That's exactly right. Early on ocelot_ext was doing all sorts of things
that are now the control of ocelot-mfd and the various subsystems. These
couple procedures seem to be the last relics of those early days.

As I cleaned this up, I realized ocelot_ext_reset_phys() is no longer
needed, as it is handled in the MDIO driver. It looks like there won't
be much to remove when this is all said and done :-)

Thanks for reminding me. If I knew then what I know now... maybe I'd ask
the hardware person to spec a different chip ;-)

I'm joking of course, and looking forward to being able to use this
thing!
