Subject: [PATCH] xhci: add port speed ID to portsc tracing
Git-commit: 8f11487719401e20ecc58c114d9fc3177535c40a
Patch-mainline: v4.15-rc1
References: FATE#325103
Shows the port speed protocol speed ID (PSID) in use.
speed ID may map to custom speeds, but in most cases it uses default
1 = Full-Speed 12 MB/s
2 = Low-Speed 1.5 Mb/s
3 = High-speed 480 Mb/s
4 = SuperSpeed 5 Gb/s
5 = SuperSpeedPlus 10 Gb/s
