Suspend scenario in case of ohci-platform glue was not
properly handled as it was not suspending generic part
of ohci controller. Calling explicitly the ohci_suspend()

-Incase ohci_suspend() fails, return right away without
executing further.
V3:

Again, the above variables weren't aligned. I bet you were just
