Sync Linux kernel dwc3 changes from v5.15 to v5.16.
The following files are preserved accross the import:

dwc3-uniphier.c dwc3-generic.h dwc3-generic.c dwc3-generic-sti.c
dwc3-layerscape.c ti_usb_phy.c
Skipping unused files:

dwc3-rtk.c dwc3-st.c dwc3-xilinx.c host.c trace.c trace.h ulpi.c
Note that this is a raw import and doesn't build.
A fixup commit at the end of the series fixes that.
