usb: misc: onboard-hub: add support for Microchip USB2514B USB 2.0 hub

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.
