Subject: [PATCH 1/4] dt-bindings: usb: generic-ehci: allow usb-hcd schema properties

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
