interconnect: Move internal structs into a separate file 



[ Upstream commit dd018a9cf9108f9c7d924f6fe09aed745e78a67e ]

Move the interconnect framework internal structs into a separate file,
so that it can be included and used by ftrace code. This will allow us
to expose some more useful information in the traces.
