juno: Add stub device tree node for CCI-400

This patch adds a basic device tree node for the CCI-400
interconnect, so that the system profiler driver can refer to it.

This node is provisional and may change.  For now it serves only to
provide the CCI-400 programmer's view register block base address
and size.
