PCI: Set up bridge resources earlier

Bridge windows are read twice from PCI Config Space, the first time from
pci_read_bridge_windows(), which does not set up the device's resources.
This causes problems down the road as child resources of the bridge cannot
check whether they reside within the bridge window or not.

Set up the bridge windows already in pci_read_bridge_windows().
