usb: ohci-at91: Fix the unhandle interrupt when resume

commit c55afcbeaa7a6f4fffdbc999a9bf3f0b29a5186f upstream.

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.

According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().
