| PCI: update bridge resources to get more big ranges in PCI assign unssigned

Unfortunately, the bug tracker is dead, so I cannot ask for further
information. (If somebody renews the domain, this report will be at

The Xonar DX is a PCI chip with a 256-byte I/O range behind a PCI-E/PCI
bridge. The driver code that caught this looks as follows:

err = pci_enable_device(pci);
err = pci_request_regions(pci, DRIVER);
if (!(pci_resource_flags(pci, 0) & IORESOURCE_IO) ||
pci_resource_len(pci, 0) < OXYGEN_IO_SIZE) {
snd_printk(KERN_ERR "invalid PCI I/O range\n");
