[PATCH 05/10] USB: OHCI: Properly handle ohci-exynos suspend

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