Subject: [PATCH 2/3] dt-bindings: PCI: mediatek,mt7621: add missing child node reg

MT7621 PCI host bridge has children which apparently are also PCI host
bridges, at least that's what the binding suggest.  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.
