This adds the device trees and minimal code needed to run
U-Boot on Broadcom Northstar SoCs.

This is needed to properly boot the D-Link DIR-890L router
as it refuse to directly boot compressed kernels bigger
than 2MB, and well our compressed kernel is bigger than
2MB so let's put in U-Boot.

While it is a bit tailored to this usecase (it can probably
also be used with the DIR-885L without modifications) it
forms a base that can be used to support more Northstar
boards.

I have this working with DIR-890L and OpenWrt:
