Suspend scenario in case of ohci-at91 glue was not properly
handled as it was not suspending generic part of ohci controller.
Calling explicitly the ohci_suspend() routine in ohci_hcd_at91_drv_suspend()
will ensure proper handling of suspend scenario.

V2:
-Incase ohci_suspend() fails, return right away without executing further.
V3:
-Aligned variable "do_wakeup" and "ret".
