[PATCH 07/10] USB: OHCI: Properly handle ohci-platform suspend

Suspend scenario in case of ohci-platform glue was not
properly handled as it was not suspending generic part
of ohci controller.Calling explicitly the ohci_suspend()
routine in ohci_platform_suspend() will ensure proper
handling of suspend scenario.
