iop13xx confuses I/O port numbers with physical addresses, which breaks legacy ISA I/O access behind PCI bridges and makes it unnecessarily hard to unify the inb/outb accessors with other platforms. This removes the special-casing and just puts all I/O ports into a single 128KB virtually mapped I/O port range starting at port zero. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
