This is a first pass converting i.MX to a devicetree-only platform.

i.MX board files have been primarily receiving only tree-wide API
cleanups and does not appear to have real users.

i.MX27, i.MX31 and i.MX35 have basic devicetree support and users
can improve devicetree support if needed.

i.MX21 has not been converted to device tree yet, so drop its support.

Of course if someone is interested in using i.MX21 with a mainline kernel,
patches that add i.MX21 devicetree support will be welcome.

For maintainance perspective, it is easier to treat i.MX as a devicetree-only
platform, so remove the board files to achieve this end goal.

This looks reasonable to me overall, there has not been any work on
converting the remaining boards in a long time, and both the imx3 and
imx21 are unlikely to have been used in new products for at least
as long.

I would prefer somewhat to recursively remove now-unused code from
mach-imx/*, in particular I would guess that most of mach-imx/devices/
can get removed along with the board files using it. If you feel strongly
that this is too much and the work needs to be split into multiple steps,
that is also fine with me.
