John Crispin 4f3c1e7793 procd: hotplug.json: allow passing hotplug events from all subsystems
There are time that programs need to be notified of events from
subsystems that are not enumerated in the .json definition, e.g. QEMU
guest agent by default requires /dev/virtio-ports/org.qemu.guest_agent.0
which is a symlink to /dev/vportMpN from virtio-ports subsystem.
