Subject: usb: dwc3: Fix GDBGFIFOSPACE_TYPE values
From: Thinh Nguyen <Thinh.Nguyen@xxxxxxxxxxxx>
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")
