The VExpress development platform has an external expansion bus which
can be used for additional hardware (e.g. LogicTile Express
daughterboards).
Add this bus to the VExpress CoreTile device-trees.

The bus is described for a CoreTile occupying site 1.

The Juno development platform has an external expansion bus which can
be used for additional hardware (e.g. LogicTile Express daughterboards).
Add this bus to the Juno base device-tree.
