[PATCH 01/10] USB: OHCI: Properly handle ohci-at91 suspend

[Manjunath Goudar]

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.
