AMD fam10: Drop PCI_BUS_SEGN_BITS

Browse Source 
All boards in tree use 0.  Looks like this is all work that was
never completed and tested.

We also have static setting sysconf.segbit=0 which would conflict
with PCI_BUS_SEGN_BITS>0.

Having PCI_BUS_SEGN_BITS>0 would also require PCI MMCONF support
to cover over 255 buses.
