Fix ich9 bios to correctly configure pci bridge1 and pci bridge2

|
|
|
avg: I think that it is a valid report, the patch is not perfect, but
|
|
avg: it fixes the problem for most configurations and demonstrates the problem well
|
|
avg: the explanation for them is that FreeBSD (unlike Linux and maybe other OSes)
|
|
avg: entirely relies on platform doing correct bus numbering
|
|
avg: currently we can not do any re-numbering/corrections
