[PATCH 34/40] lasips2: update VMStateDescription for LASIPS2 device

[Mark Cave-Ayland]

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.
