USB: OHCI: Properly handle ohci-sm501 suspend
Suspend scenario in case of ohci-sm501 glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly
handle ohci-sm501 suspend scenario.
Calling explicitly the ohci_suspend() routine in
ohci_sm501_suspend() will ensure proper handling of suspend
scenario.
