lasips2: update VMStateDescription for LASIPS2 device 

Since this series has already introduced a migration break for the HPPA B160L
machine, we can use this opportunity to improve the VMStateDescription for
the LASIPS2 device.

Add the new int_status field to the VMStateDescription and remodel the ports
as separate VMSTATE_STRUCT instances representing each LASIPS2Port. Once this
is done, the migration stream can be updated to include buf and loopback_rbne
for each port (which is necessary since the values are accessed across separate
IO accesses), and drop the port id as this is hardcoded for each port type.
