xhci: Don't issue Reset Device command to Etron xHCI host

commit 76d98856b1c6d06ce18f32c20527a4f9d283e660 upstream.

Sometimes the hub driver does not recognize the USB device connected
to the external USB2.0 hub when the system resumes from S4.

After the SetPortFeature(PORT_RESET) request is completed, the hub
driver calls the HCD reset_device callback, which will issue a Reset
Device command and free all structures associated with endpoints
that were disabled.

This happens when the xHCI driver issue a Reset Device command to
inform the Etron xHCI host that the USB device associated with a
device slot has been reset. Seems that the Etron xHCI host can not
perform this command correctly, affecting the USB device.

To work around this, the xHCI driver should obtain a new device slot
with reference to commit 651aaf36 ("usb: xhci: Handle USB transaction
error on address command"), which is another way to inform the Etron
xHCI host that the USB device has been reset.

Add a new XHCI_ETRON_HOST quirk flag to invoke the workaround in
xhci_discover_or_reset_device().
