x86/PCI: Mark constants of pci_mmcfg_nvidia_mcp55() as __initconst
The constants in pci_mmcfg_nvidia_mcp55() need to be marked as __initconst or they will remain in memory after init memory was released. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Ingo Molnar <mingo@kernel.org>
