[PATCH v3] FIT support

[Sascha Hauer]

This is the third version of the FIT image support. Changes
to last series include:

- Integrate FIT support more deeply into bootm remove complexity
  from the architecture handlers
- Cleanup bootm support
- Add support for configuration names as suggested by Yegor Yefremov
- Allow to boot unsigned FIT images

It's time for a weekend now, so I send out what I have now. This series
could use some more testing before it gets merged, so I'll do that next
week before merging it. In the meantime everyone else is invited for
testing aswell ;)
