USB: OHCI: Properly handle ohci-pxa27x suspend
Suspend scenario in case of ohci-pxa27x glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly
handle ohci-pxa27x suspend scenario.
Calling explicitly the ohci_suspend() routine in
ohci_hcd_pxa27x_drv_suspend() will ensure proper
handling of suspend scenario.
