[PATCH] arm: Iomega ix4-200d support

[Eric Sandeen]

The following is was (lightly) tested under 2.6.30 with a development
board for the Iomega ix4-200d NAS box, which eventually released as:

http://go.iomega.com/en-us/products/network-storage-desktop/storcenter-network-storage-solution/network-hard-drive-ix4-200d/ 

It could probably use some tidying up, but perhaps it's a good starting
place, at least.
