From: Manjunath Goudar <manjunath.goudar@xxxxxxxxxx>
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.
