device tree: give dt more size

We currently load a device tree blob and then just take its size x2 to
account for modifications we do inside. While this is nice and great,
it fails when we have a small device tree as blob and lots of nodes added
in machine init code.

So for now, just make it 20k bigger than it was before. We maybe want to
be more clever about this later.
