Subject: [PATCH 4.14 41/41] usb: dwc3: Fix GDBGFIFOSPACE_TYPE values

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thinh Nguyen <Thinh.Nguyen@...opsys.com>

commit b16ea8b9492e99e03b1269fe93ebdbf8e4eabf8a upstream.

The FIFO/Queue type values are incorrect. Correct them according to
DWC_usb3 programming guide section 1.2.27 (or DWC_usb31 section 1.2.25).

Additionally, this patch includes ProtocolStatusQ and AuxEventQ types.

Fixes: cf6d867d3b57 ("usb: dwc3: core: add fifo space helper")
