Subject: [PATCH 0/4] usb: Use notifier for linking Type C ports.

This series resolves the cyclic dependency error which was introduced by
commit 63cd78617350 ("usb: Link the ports to the connectors they are
attached to") which lead to it being reverted. The approach here is to
use a notifier to link a new Type C port to pre-existing USB ports
instead of calling an iterator of usb ports from the Type C connector
class. This allows commit 63cd78617350 ("usb: Link the ports to the
connectors they are attached to") to then be submitted without any
depmod cyclic dependency error.

The final patch removes the usb port iterator since it is no longer
needed.
