usb: core: hub: Create platform devices for onboard hubs in hub_probe()
Call onboard_hub_create/destroy_pdevs() from hub_probe/disconnect()
to create/destroy platform devices for onboard USB hubs that may be
connected to the hub. The onboard hubs must have nodes in the
device tree.
onboard_hub_create/destroy_pdevs() are NOPs unless
CONFIG_USB_ONBOARD_HUB=y/m.
Also add a field to struct usb_hub to keep track of the onboard hub
platform devices that are owned by the hub.
