Subject[RFC PATCH 2/3] usb, PCI: remove disable/enable device with non-xhci quirk
Date
| commit cab928ee1f221c9cc48d6615070fefe2e444384a
| USB: Fix handoff when BIOS disables host PCI device.

mention only need to do disable/enable for xhci controller.

So just remove that for non-xhci controller and restore old behavior for them.
