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)

Please use string names instead of hard-coded integers.

	interconnects = <&rsc_hlos MASTER_MDP0 &rsc_hlos SLAVE_EBI1>,
			<&rsc_hlos MASTER_MDP1 &rsc_hlos SLAVE_EBI1>;

We are trying to be more descriptive and include both the source and the
destination like: "mdp0-mem", "mdp1-mem"

Otherwise looks good.

Thanks,
