[PATCH 04/17] pci: sysfs: move declarations to linux/pci.h

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

A couple of architectures build the __weak versions of
pci_create_resource_files() and pci_remove_resource_files() but don't
have prototypes for these, which causes warnings:

drivers/pci/pci-sysfs.c:1253:12: error: no previous prototype for 'pci_create_resource_files' [-Werror=missing-prototypes]
 1253 | int __weak pci_create_resource_files(struct pci_dev *dev) { return 0; }
drivers/pci/pci-sysfs.c:1254:13: error: no previous prototype for 'pci_remove_resource_files' [-Werror=missing-prototypes]
 1254 | void __weak pci_remove_resource_files(struct pci_dev *dev) { return; }

Move the prototypes from alpha architecture into the global header to
avoid these warnings for all of them.
