* [PATCH 1/4] Add the basic files for the i.MX23/i.MX28 familiy of CPUs

To: barebox
These CPUs are called "i.MX", but they are of type STM378x from SigmaTel. They
do not share any devices with the other i.MX CPUs, so we need a separate
architecute directory to handle them without an ifdef hell in the native i.MX
files.
