ehci-hub: improved over-current recovery
According to the USB Specification Revision 2.0 chapter 11.12.5 a hub experiencing an over-current condition must place all affected ports in the powered-off state. It seems that some root hubs need port power to be cycled by software in order to get back to normal functionality after an over-current condition ... like the EHCI implementation on an MPC8343E.
