Add support for USB2514B HUB found on stm32mp1 boards:
- Extend the ehci-generic dt-binding to fully use the usb-hcd.yaml, and so
  the usb-device.yaml.
- Add usb-device compatible ("usbVID,PID") for the USB2514B USB2.0 HUB to
  the onboard_usb_hub driver.
- Add relevant device tree node to stm32mp15 DK boards.
- Enable the onboard_usb_hub driver on multi_v7 platforms.

Changes in v2:
- Follow Matthias review comments
- dt-bindings reviewed by Rob

Fabrice Gasnier (4):
  dt-bindings: usb: generic-ehci: allow usb-hcd schema properties
  usb: misc: onboard-hub: add support for Microchip USB2514B USB 2.0 hub
  ARM: dts: stm32: add support for USB2514B onboard hub on
    stm32mp15xx-dkx
  ARM: multi_v7_defconfig: enable USB onboard HUB driver
