Convert to four static const attributes (legacy_io, legacy_io_sparse, legacy_mem, legacy_mem_sparse) with .is_bin_visible() callbacks that use pci_legacy_has_sparse() to select the appropriate variant per bus. The sizes are compile-time constants and .size is set directly on each attribute. Register the groups in pcibus_groups[] under a HAVE_PCI_LEGACY guard so the driver model handles creation and removal automatically. Stub out pci_create_legacy_files() and pci_remove_legacy_files() as the dynamic creation is no longer needed. Remove the __weak pci_adjust_legacy_attr(), Alpha's override, and its declaration from both Alpha and PowerPC asm/pci.h headers.
