In driver model, each pci bridge device has its own hose structure. hose->first_busno points to the bridge device's device number, so we should not substract hose->first_busno before programming the bridge device's primary/secondary/subordinate bus number registers.

I'm not happy with how each PCI bridge has its own hose structure. I think that was a mistake. It just creates problems.
I'm thinking we should instead have a UCLASS_PCI which is strictly for the PCI controller, and a new UCLASS_PCI_BRIDGE for bridges.
What do you think?
I guess that may help. During the debug, I feel the dm pci codes are really not that intuitive than the previous non-dm version. It took me sometime to figure out where is the problem.
