Now that imx27 has been converted to a devicetree-only platform,
retrieve the SYSCTRL base address from devicetree.

While this is nicer in theory, I don't like the way it breaks compatibility

What is the status of dtb stability otherwise on imx? My impression
was that it is actually quite good about not breaking this way.
