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):

2.25.1
Allow properties and usb-device child nodes as defined in usb-hcd.yaml, by
using unevaluatedProperties: false. By the way, remove the "companion"
property as it's redundant with usb-hcd.yaml.
As example, this allows an onboard hub, to be described in generic-ehci
controller node:
usb {
compatible = "generic-ehci";
#address-cells = <1>;
#size-cells = <0>;
/* onboard HUB */
hub@1 {
compatible = "usb424,2514";
reg = <1>;
vdd-supply = <&v3v3>;
};
};
Without this, dtbs_check complains on '#address-cells', '#size-cells',
'hub@1' do not match any of the regexes: 'pinctrl-[0-9]+'
From schema: ..../generic-ehci.yaml
