usb: ohci-at91: Fix the unhandle interrupt when resume
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().
