[PATCH 08/10] USB: OHCI: Properly handle ohci-pxa27x suspend

[Manjunath Goudar]

Suspend scenario in case of ohci-pxa27x glue was not
properly handled as it was not suspending generic part
of ohci controller.Calling explicitly the ohci_suspend()
routine in ohci_hcd_pxa27x_drv_suspend() will ensure proper
handling of suspend scenario.
