dt-bindings: soc: bcm: add missing dt-binding document for bcm23550-cdc 



Broadcom BCM23550 has a Cluster Dormant Control block that keeps the CPU
in idle state. A command needs to be sent to this block to bring the CPU
into running state.

This has been in use in mainline Linux since ~2016, but was never
documented. Add a dt-binding document for it.
