I made a patch series to remove all ioport_register_* function in
differents devices (dma, cirrus, ...):
https://lists.gnu.org/archive/html/qemu-devel/2012-08/msg04007.html
ioport_register_* don' t use the new memory API, so listener is not
called when a new range is registered.
I will rework the commit message and send it back.
