The addition of the i.MX93 USB support in the kernel devicetree is
taking longer than expected:

https://lore.kernel.org/linux-arm-kernel/20240321081439.541799-8-xu.yang_2@nxp.com/T/#u

To avoid getting out of sync with the upstream dts, please add the USB
nodes inside imx93-phyboard-segin-u-boot.dtsi
for now.

Thanks
