SRU Justification:

Impact: This only affects the Etron USB 3.0 controller.
When insert USB 3.0/2.0 device into any of the USB 3.0 port, device will not
be recognized. And the dmesg shown as below.
[ 58.330621] usb 3-1: Cannot reset HCD device state
[ 58.590690] xhci_hcd 0000:05:00.0: Unknown completion code 192 for reset device command.

Fix: Patches taken from upstream kernel

Testcase: Tested on ACER machine

Maarten Lankhorst (2):
xhci: Do not issue device reset when device is not setup
xhci: Add defines for hardcoded slot states
