DWC3 as implemented in Cavium SoC is using UCTL bridge unit between I/O interconnect and USB controller. Currently there is no bond with dwc3 core code, so if anything goes wrong in UCTL setup dwc3 is left in reset, which leads to bus error while trying to read any device register. Thus any failure in UCTL initialization ends with kernel panic. To avoid this move Octeon DWC3 glue code from arch/mips and make it proper glue driver which is used instead of dwc3-of-simple.

# We want to keep this requirement in order to be able to compile

# the entire driver (with all its glue layers) on several architectures
