[PATCH] ARM: dts: vexpress: Add CCI node to TC2 device-tree

The Versatile Express V2P-CA15_A7 (aka TC2) has a CCI-400 which is
needed to get Multi-Cluster Power Management (MCPM) working.

I was unsure if the devicetree list should be cc'd when making use of
already agreed and documented bindings, so I erred on the side of
caution and added it. Please say if this is unnecessary noise, or is
expected for all device-tree changes, thanks.
