arm64: dts: rockchip: rename nodename for phy-rockchip-inno-usb2

The pattern: "^(|usb-|usb2-|usb3-|pci-|pcie-|sata-)phy(@[0-9a-f,]+)*$"
in phy-provider.yaml has required "#phy-cells" for phy nodes.
The "phy-cells" in rockchip-inno-usb2 nodes are located in subnodes.
Rename the nodename to pattern "usb2phy@[0-9a-f]+$" to prevent
notifications.
