Sync Linux kernel dwc3 changes from v6.4 to v6.5. The following files are preserved accross the import: Makefile Kconfig dwc3-meson-g12a.c dwc3-meson-gxl.c dwc3-omap.c dwc3-uniphier.c dwc3-generic.h dwc3-generic.c dwc3-generic-sti.c dwc3-layerscape.c ti_usb_phy.c

A fixup commit at the end of the series fixes that.
