USB: OHCI: Properly handle ohci-s3c2410 suspend

Suspend scenario in case of ohci-s3c2410 glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly handle
ohci-s3c2410 suspend scenario.

Calling explicitly the ohci_suspend()
routine in ohci_hcd_s3c2410_drv_suspend() will ensure
proper handling of suspend scenario.
