From: Manjunath Goudar <manjunath.goudar@xxxxxxxxxx>
Suspend scenario in case of ohci-at91 glue was not properly handled
as it was not suspending generic part of ohci controller. Alan Stern
suggested, properly handle ohci-at91 suspend scenario.
Calling explicitly the ohci_suspend() routine in ohci_hcd_at91_drv_suspend()
will ensure proper handling of suspend scenario.
