USB: OHCI: Properly handle ohci-omap suspend
Suspend scenario in case of ohci-omap glue was not properly handled as it was not suspending generic part of ohci controller. Alan Stern suggested, properly handle ohci-omap suspend scenario. Calling explicitly the ohci_suspend() routine in ohci_omap_suspend() will ensure proper handling of suspend scenario.
