[PATCH NOT FOR MERGE v2 66/66] of: Mark interconnects property supplier as optional

This illegitimate change makes it possible for the sun6i csi and isp
drivers to probe without a proper interconnect driver available.

Without this change, the core will wait for an interconnect driver to
probe and return EPROBE_DEFER in our drivers. This ends up in these
drivers never being probed since no driver exists.
