With [1] USB4 target-module node got defined in dra74x.dtsi file. However, the earlier definition in [2] was not removed, and this duplication of the target module is causing boot failure on dra74 variant boards - dra7-evm, dra76-evm. USB4 is only present in DRA74x variants, so keeping the entry in dra74x.dtsi and removing it from the top level interconnect hierarchy dra7-l4.dtsi file. This change makes the USB4 target module no longer visible to AM5718, DRA71x and DRA72x so removing references to it in their respective dts files.
