kernel: add kmod-usb-dwc3-octeon

Since 24.10.0, Linux 6.6 is used which includes a reorganisation of
Octeon DWC3 glue code.
https://lore.kernel.org/all/ZJC3LLpUlatnLdnv@lenoch/

As a result, Octeon devices using this, such as EdgeRouter 4 have a no
longer functioning USB stack.

Build kmod-usb-dwc3-octeon for Cavium Octeon targets.
