Call onboard_hub_create/destroy_pdevs() from usb_add/remove_hcd()
for primary HCDs to create/destroy platform devices for onboard
USB hubs that may be connected to the root hub of the controller.
These functions are a NOP unless CONFIG_USB_ONBOARD_HUB=y/m.
Also add a field to struct usb_hcd to keep track of the onboard hub
platform devices that are owned by the HCD.
