When a oftree is concatenated,the zImage is bigger than the size specified in
the zImage header. Detect it and copy it too.

I am missing a call to of_fix_tree() here. Without it the command line
will not be passed to the kernel. Maybe this is not really the intended
usecase for appending an oftree to the zImage. Being able to append the
oftree to the zImage seems more for bootloaders which do not have native
support for devicetrees.
We could be more clever here and read the oftree to a seperately
allocated area and set data->oftree then.

This will allow to update it with fixup.

This looks like a followup to the previous patch, but it does not apply
neither with or without this patch.
