AMD SB600 uses a hardcoded USB Debug Port number. 

It cannot be changed via software according to the datasheet, whereas
this is indeed possible on AMD SB700. I tested using the SB700 mechanism
on SB600 but it didn't work, so I suspect the datasheet is indeed correct.

Thus, don't show the kconfig option for selecting the physical USB port
on the AMD SB600 southbridge.
