[PATCH] ep93xx: Add support for Simplemachines Sim.One board

[ryan@bluewatersys.com (Ryan Mallon)]

The following patch adds support for the ep9307 based Sim.One board from
Simplemachines. The code is based on the patches from Simplemachines for
the 2.6.24.7 kernel available here:
http://sim1.googlecode.com/files/linux-2.6.24.7-patches-20091001.tgz.
Support for  SPI and Audio is not included since we do not support them
in mainline yet. The framebuffer support has been tested with a standard
desktop monitor. LCD support is not included because I do not have
hardware to test.

I have specified the maintainer for this board as Nuccio Raciti (CC'ed),
who is the maintainer for Simplemachine's 2.6.24.7 patches. If this is
not okay, I can put myself as the maintainer.
