Add interconnect properties such as interconnect provider specifier
, the edge source and destination ports which are required by the
interconnect API to configure interconnect path for MDSS.

Changes in v2:
	- None

Changes in v3:
	- Remove common property definitions (Rob Herring)

Changes in v4:
	- Use port macros and change port string names (Georgi Djakov)

Changes in v5-v7:
	- None

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.
