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.

+= interconnect consumers =
+
+The interconnect consumers are device nodes which consume the interconnect
+path(s) provided by the interconnect provider. There can be multiple
+interconnect providers on a SoC and the consumer may consume multiple paths
+from different providers depending on usecase and the components it has to
+interact with.
+
+Required-properties:
+interconnects: Pairs of phandles and interconnect provider specifier to denote
+		the source and the destination port of the interconnect path.
+interconnect-names: List of interconnect path name strings sorted in the same
+		order as the interconnects property. Consumers drivers will use
+		interconnect-names to match interconnect paths with interconnect
+		specifiers.
+
+Example:
+
+	sdhci@7864000 {
+		...
+		interconnects = <&pnoc 78 &bimc 512>
+		interconnect-names = "memory";
+	};
