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.

V2:
-Incase ohci_suspend() fails, return right away without
executing further.
V3:
-Aligned variable "do_wakeup" and "ret".
V4:
-The do_wakeup and ret variable alignment is removed.
