Log:
Drop unused and useless CONFIG_MAX_PCI_BUSES.

It was added by rsmith in r2273 on 20060424, when pci_locate_device() in
src/arch/i386/include/arch/romcc_io.h in fact scanned all busses:

- for(; dev <= PCI_DEV(255, 31, 7); dev += PCI_DEV(0,0,1)) {
 + for(; dev <= PCI_DEV(CONFIG_MAX_PCI_BUSES, 31, 7); dev += PCI_DEV(0,0,1)) {

Today this looks like:

for(; dev <= PCI_DEV(255|(((1<<CONFIG_PCI_BUS_SEGN_BITS)-1)<<8), 31, 7); dev += PCI_DEV(0,0,1)) {

and CONFIG_MAX_PCI_BUSES is never used anywhere.
