[PATCH 1/7] dt-bindings: arm: vexpress-sysreg: Add "mcc" child node

["Rob Herring (Arm)" <robh@kernel.org>]

The "arm,vexpress,config-bus" is accessed via the "arm,vexpress-sysreg"
registers, so it is appropriate for it to be located there rather than
in a "simple-bus" as current DTS files have. Under the "simple-bus" is
not appropriate given there is no MMIO space.
