dt-bindings: PCI: mediatek,mt7621: Add missing child node reg

MT7621 PCI host bridge has children which are PCI root ports. The children have "reg" property, but do not explicitly define it. Instead they rely on pci-bus.yaml schema, but that one has "reg" without any constraints. Define the "reg" for the children, so the binding will be more specific and later will allow dropping reference to deprecated pci-bus.yaml schema.
