The MediaTek MTU3 and xHCI text bindings describe legacy U-Boot layouts which have been superseded by the canonical Linux schemas. Those schemas are already synchronized into `dts/upstream/Bindings/usb`.
Remove the duplicate text bindings so new devicetrees and driver changes use the maintained YAML definitions.
