Since all the bugs and work-arounds in previous STB chips are supposed to be fixed, most of the code in phy-brcm-usb-init.c is not needed. Instead of adding more complexity to the already complicated phy-brcm-usb-init.c module, the driver will be restructured to use a vector table to dispatch into different C modules for the different controllers. There was also some general cleanup done including some ipp setup code that was incorrect.
