Enable DT support for AT91SAM9263EK

This patchset enabledevice tree support for AT91SAM9263EK.

On the quest towards getting so far several drivers was converted to support DT.
These patches went in around august.

There was also issues with mach-at91 calling code in the board directory (dependency in the wrong direction).
This was fixed in "at91: move reset .." which is pending (already posted).

I have failed to get the bootstrap mode to work. It stops somewhere - and I have not invested enough time to figure out where and why things goes wrong. bootstrap mode was also broken before these patches. No JTAG debugger available to help me.
And then I have at91bootstrap that works so motivation was not too high.

I do not think the NAND support works either.
The device tree introduces some nand-controller stuff that is not supported by barebox (at least I assume so). And this part I did not look further into.

Next step is to get a proprietary board up and running (which uses NOR flash).
But I wanted this patchset out in the open first.

Any fedback highly appreciated!
