[PATCH] PCI: Constify struct configfs_attribute pointers

[PATCH] PCI: Constify struct configfs_attribute pointers

[Thomas Weißschuh]

In preparation for the constification of configfs attributes, make the
pointers to struct configfs_attribute in drivers/pci/ const
and use the new ct_attrs_const field of struct config_item_type.
