USB: make USB-PERSIST work after every system sleep
This patch (as1046) makes USB-PERSIST work more in accordance with the documentation. Currently it takes effect only in cases where the root hub has lost power or been reset, but it is supposed to operate whenever a power session was dropped during a system sleep. A new hub_restart() routine carries out the duties required during a reset or a reset-resume. It checks to see whether occupied ports are still enabled, and if they aren't then it clears the enable-change and connect-change features (to prevent interference by khubd) and sets the child device's reset_resume flag. It also checks ports that are supposed to be unoccupied to verify that the firmware hasn't left the port in an enabled state.
