Add documentation for the interconnect consumer bindings, that will allow to link a device node (consumer) to its interconnect controller hardware. Tha aim is to enable drivers to request a framework API to configure an interconnect path by providing their struct device pointer and a name.

Analog to other subsystems the -names property should be optional, at least when there's only a single entry in interconnects.
