In contrast to other hotplug events PEC 0x306 isn't about a single
but multiple devices. Also there's no information on what happened
to these devices. We correctly handled hotplug that way but failed
to handle hot-unplug. This patch addresses that and implements
hot-unplug of multiple devices via PEC 306.
