PCI: Skip allocate_resource() if too little space available
pci_bus_alloc_from_region() allocates MMIO space by iterating through all
the resources available on the bus. The available resource might be
reduced if the caller requires 32-bit space or we're avoiding BIOS or E820
areas.
Don't bother calling allocate_resource() if we need more space than is
available in this resource. This prevents some pointless and annoying
messages about avoided areas.
