usb: dwc3: dwc3-octeon: Convert to glue driver
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.
