[RFC PATCH 09/11] hw/ide: Let ide_init_ioport() take an ISA bus argument instead of device

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Both callers to ide_init_ioport() have access to the ISA bus of the
device, so can pass it directly. This allows ide_init_ioport() to
directly call isa_bus_register_portio_list().

Note, now the callers become the owner of the PortioList.
