Interfaces and structs for saving and restoring PCI Capability state were
declared in include/linux/pci.h, but aren't needed outside drivers/pci/.
Move these to drivers/pci/pci.h:
struct pci_cap_saved_data
struct pci_cap_saved_state
void pci_allocate_cap_save_buffers()
void pci_free_cap_save_buffers()
int pci_add_cap_save_buffer()
int pci_add_ext_cap_save_buffer()
struct pci_cap_saved_state *pci_find_saved_cap()
struct pci_cap_saved_state *pci_find_saved_ext_cap()

Applied with Alex's Reviewed-by to pci/misc for v5.15.
