rpmsg: mtk: release channel OF node on device teardown

Browse Source 
mtk_rpmsg_match_device_subnode() returns a referenced OF child
node, which is stored in rpdev->dev.of_node.

mtk_rpmsg_release_device() later frees the containing allocation
without dropping that ref.

Release the OF node when the RPMsg device is destroyed.
