usb: chipidea: fix nobody cared IRQ when booting with host role
If we connect Male-A-To-Male-A cable between otg-host and host pc,
the ci->vbus_active is set wrongly, and cause the controller run
at peripheral mode when we load gadget module (ci_udc_start will be run),
but the software runs at host mode due to id = 0. The ehci_irq
can't handle suspend (USBi_SLI) interrupt which is enabled for
peripheral mode, it causes no one will handle irq error.
This patch is needed for 3.12 stable
