PCI: Don't convert BAR address to resource if dma_addr_t is too small
If dma_addr_t is too small to represent the BAR value, pcibios_bus_to_resource() will fail, so just remember the BAR size directly in the resource. The resource is already marked UNSET, so we know the address isn't valid anyway. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
