Expose Cadence USBSSP through the same platform path as USBSS, trim Kconfig and Makefile: one core loadable object plus separate glue .ko files. Single cdns.ko bundles core, DRD, the generic "cdns,usb3" platform driver in cdns3-plat.c, optional host.o, and optional gadget objects. Use CONFIG_USB_CDNS3_GADGET as a bool to compile gadget support into that module. Remove duplicate MODULE_* declarations from cdns3-plat.c now that it links into the same module. Kconfig: the generic platform driver is selected via CONFIG_USB_CDNS3. Move CONFIG_USB_CDNSP_PCI beside CONFIG_USB_CDNS3_PCI_WRAP under "Platform glue driver support". SoC glue entries (TI, i.MX, StarFive) depend only on CONFIG_USB_CDNS3. Tighten CONFIG_USB_CDNS_SUPPORT dependencies so the umbrella follows host or gadget when either is built as a module. Match host and gadget bools to the cdns.ko tristate with USB=USB_CDNS3 and USB_GADGET=USB_CDNS3 instead of comparing against USB_CDNS_SUPPORT. Link host.o when CONFIG_USB_CDNS3_HOST is enabled and use that symbol in host-export.h, removing the redundant CONFIG_USB_CDNS_HOST indirection. Export cdns_core_init_role and reorganize the function cdns_init, and controller version could be gotten before the gadget init function is decided per controller. Keep host_init / gadget_init callbacks in struct cdns, so core.c does not need direct linkage to host or gadget objects. Refactor cdnsp-pci.c into a thin PCI-to-platform wrapper. drivers/usb/Makefile: descend into drivers/usb/cdns3/ only when CONFIG_USB_CDNS_SUPPORT is enabled.
