ls1043a-rdb and ls1043a-qds board’s default HW config (such as pin mux selection) would not enable some USB controllers’ data path, which causing over-current detected on those controllers. This will hit the case of ‘xhci driver prevent bus suspend if a root hub port detected over-current condition’, causing system failed to be suspended. So disable them in device tree to resolve this issue.
