For the pinctrl stuff I suggest doing what we have done for the newer
i.MX SoCs before we had pinctrl: Match by board compatible string and
call into the board code for using the static pinctrl tables which are
already there. I would like to have propert pinctrl support for the
older i.MX, but probably the motivation for writing it is quite low for
the older SoCs.

We have a patch in the queue converting the clock lookups for i.MX27 to
dt which should be ready for posting soon.

Then the main road blockers should be out of the way to get rid of the
bulk of the board code.
