Bring together i.MX23, its MCI driver and the ChumbyOne

[Juergen Beisert]

Now the i.MX23 architecture and the MCI support is in place, bring both
together and make the ChumbyOne use of it.

[PATCH 2/4] Adapt the i.MX23 MCI driver to the v2 i.MX23 patch series

[Juergen Beisert]

The i.MX23 v2 architecture patch series was sligthly modified to easify
the i.MX28 architecture addition later on. So, we need now an index to
query the SSP clock frequency.

[PATCH 3/4] Spend the ChumbyOne a persistant environment memory on MCI card

[Juergen Beisert]

The ChumbyOne boot from MCI card only. As ist more fun to run barebox with
a persistant environment, provide one in the second partition on the MCI card.
