Kyösti Mälkki cdfb46240b AGESA boards: Use devicetree for PCI bus enumeration
Previously MP table contained PCI_INT entries for PCI bus behind bridge
0:14.4 even if said PCI bridge function was disabled.
Remove these as invalid, indeterminate bus number could cause conflicts.

PCI_INT entries with bus_sb800[2], bus_hudson[2] and bus_yangtze[2]
were invalid as there is no PCI bridge hardware on device 0:14.0.
Remove these as invalid, indeterminate bus number could cause conflicts.
