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

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

 -The do_wakeup and ret variable alignment is removed.
