PCI: Make local functions static
Using 'make namespacecheck' identify code which should be declared static. Checked for users in other driver/archs as well. Compile tested only. This stops exporting the following interfaces to modules: pci_target_state() pci_load_saved_state() [bhelgaas: retained pci_find_next_ext_capability() and pci_cfg_space_size()] Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
