PCI/sysfs: Remove pci_{create,remove}_sysfs_dev_files()
Currently, pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files()
are no-op stubs. With both the generic and Alpha resource files now
handled by static attribute groups, no platform needs dynamic per-device
sysfs file creation.
Remove both functions, their declarations, and the call sites in
pci_bus_add_device() and pci_stop_dev().
Remove __weak pci_create_resource_files() and pci_remove_resource_files()
stubs and their declarations in pci.h, as no architecture overrides them
anymore.
Remove the res_attr[] and res_attr_wc[] fields from struct pci_dev which
were used to track dynamically allocated resource attributes.
Finally, simplify pci_sysfs_init() to only handle legacy file creation
under HAVE_PCI_LEGACY, removing the per-device loop and the
HAVE_PCI_SYSFS_INIT helper added earlier.
