USB: OHCI: Properly handle ohci-ep93xx suspend

Browse Source 
Suspend scenario in case of ohci-ep93xx glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly handle
ohci-ep93xx suspend scenario.

Calling explicitly the ohci_suspend() routine in
ohci_hcd_ep93xx_drv_suspend() will ensure proper handling of
suspend scenario.
