From: Thinh Nguyen <Thinh.Nguyen@synopsys.com> [ Upstream commit 0c59f678fcfc6dd53ba493915794636a230bc4cc ] None of the DWC_usb3x IPs (and all their versions) supports low-speed setting in device mode. In the early days, our "Early Adopter Edition" DWC_usb3 databook shows that the controller may be configured to operate in low-speed, but it was revised on release. Let's remove this invalid speed setting to avoid any confusion.

This is a "cleanup only" and does not fix or solve anything, so it can be dropped from all of the kernels it has been "autoselected" for. thanks, greg k-h
