Add boot script (boot.scr) support. If no boot script are
found, it boots as usual.
Instead of extending the specialized boot script, it would belovely to
see the odroid board switch to distro boot commands for a more
standardized boot sequence.
This would be a better solution but also a much bigger work.
Morevover, the backward compatibility will be harder to verify.
So, for now, I will stick with this patch. But if you want to do it, please do
it. :)

For reference, if you need an example how to add that while staying
backwards compatible see my patchset for am335x boards which did
something like that:
