This renames the dcdofs config option in the imx-image tool to ivtofs.  dcdofs
is a misnomer. The DCD (Device Configuration Data) is only one part of the data
linked into the IVT (Image Vector Table), but the meaning of the option is
really the latter, not the former.

This makes the imxcfg files more readable and also makes it possible to
share more assignments between machines that just differ by the used
SoC. (Though I have to admit that in the cases converted here it just
more easily allows to see that the RAM config differs more than probably
necessary.)

This change is intended to have no effect on the built artifacts.
