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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
