Since x86 had a special need for registering tons of special I/O ports,
we had an ioport__setup_arch() callback, to allow each architecture
to do the same. As it turns out no one uses it beside x86, so we remove
that unnecessary abstraction.
The generic function was registered via a device_base_init() call, so
we just do the same for the x86 specific function only, and can remove
the unneeded ioport__setup_arch().
