On resume from suspend a failure with -ESHUTDOWN is returned from ohci_bus_resume, and the usb is inoperable. This happens because ohci_suspend disables the master interrupt and sets an hcd flag to say that the hw is no longer accessible. Calling ohci_resume reverts the steps taken on ohci_suspend and flags the HW as "accessible" again, resume completes successfully and usb is working after a suspend/resume sequence. While we are here, remove setting device power_state, as this is no longer needed and scheduled for removal.
