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.
V2: -Incase ohci_suspend() fails, return right away without executing further.
