PCI: Split out bridge window override of minimum allocation address
pci_bus_alloc_resource() avoids allocating space below the "min" supplied
by the caller (usually PCIBIOS_MIN_IO or PCIBIOS_MIN_MEM). This is to
protect badly documented motherboard resources. But if we're allocating
space inside an already-configured PCI-PCI bridge window, we ignore "min".
See 688d191821de ("pci: make bus resource start address override minimum IO
address").
This patch moves the check to make it more visible and simplify future
patches. No functional change.
