Subject: [PATCH v3 1/2] ARM: dts: Add expansion bus to VExpress

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.
