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.

This option selects which physical USB port coreboot will try to
use as EHCI Debug Port first (valid values are: 1-15).
