[PATCH 9/9] x86/pci: Reorder pci_mmcfg_arch_map() definition before calls

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

The typical style is to define functions before calling them.  Move
pci_mmcfg_arch_map() and pci_mmcfg_arch_unmap() earlier so they're defined
before they're called.  No functional change intended.
