hw/apm.c: Replace register_ioport_*

hw/apm.c: Replace register_ioport_*

Replace all register_ioport_*() with a MemoryRegion.
This permits to use the new Memory stuff like listeners.

Moreover, the PCI device is added as an argument for apm_init(),
so we can register IO inside the PCI IO address space.
