[PATCH] PCI: Increase the number of PCI bus resources

This patch increases the number of resource pointers in the
pci_bus structure. This is needed to store >4 resource ranges
for host bridges and transparent PCI bridges. With this change,
all PCI buses will have more resource pointers, but most PCI
buses will only use the first 3 or 4, the remaining being NULL.
The PCI core already deals with this correctly.
