ARM: i.MX27: dts: Separate barebox-specific DT changes

To ease DT import from Linux, which is still maintained in-tree, we
separate barebox-specific changes by including the original dts in
a separate DT file. This allows to overlay modifications and keep
clean DT history. Additionally, this patch updates i.MX27 DTS tree.
