[PATCH 2/2] arm64: tegra: Update USB phy-name for Jetson Orin NX

[Jon Hunter]

Running 'make dtbs_check' reports the following warning for the Jetson
Orin NX platform ...

 arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767-0000.dtb:
     usb@3550000: phy-names:1: 'usb3-0' was expected

Fix this by updating the phy-names:1 to be 'usb3-0' as expected.
