[PATCH v2 2/4] usb: misc: onboard-hub: add support for Microchip USB2514B USB 2.0 hub

[Fabrice Gasnier]

Add support for Microchip USB2514B USB 2.0 hub to the onboard usb hub
driver. Adopt the generic usb-device compatible ("usbVID,PID").
Some STM32MP1 boards have this hub on-board, with a supply that needs to
be enabled for proper operation.

Changes in v2:
- Sort vendor ids in alphabetic order as commented by Matthias.
- Sort compatible list in alphanumeric order, e.g. by vendor ids as
  commented by Matthias (but keep PIDs grouped for a HUB chip).
- Update commit message to remove earlier reference on usbVID,PID.
