Stephan Hoffmann aaed42d156 Microblaze: build kernel with device tree
This patch adds the options needed to build the SimpleImage containing
the device tree structure needed for the Microblaze architecture.

Handling Device Tree and SimpleImage will be handled in a general way
in the future.

I provide this patch to be able to build the system in the meantime.

This option will re-use the same kernel sources as the one
that have been used for the kernel headers of the
cross-compiling toolchain. Having the same version for the
kernel running on the system and for the kernel headers is
not a requirement, but using the same version allows to
download only one tarball of the kernel sources.
