Well, my understanding is that there's DT patches around for Versatile.
Is there? There is some in-tree stuff, but haven't seen any other sign of patches.
Having looked a bit at that I get the impression that this DT code has been developed (by Grant I guess) in QEMU only as a proof of concept, and never really tested on a real Versatile hardware unit.
These: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7390/1 http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7391/1
make it clear that noone ever tested an MMC card on a Versatile booted on real hardware using DT. And I strongly suspect there are more instances like that, it seems AACI, GPIO and I2C and I guess whatever you cannot test on QEMU is just unsupported.
Isn't there work by Pawel that adds support for more of the Versatile platform? My quick searching finds at least:

I think the latter is merged already, but I may be wrong.
