[PATCH v2 0/5] malta: Fix PCI IRQ levels to be preserved during migration

[Bernhard Beschow]

The intention behind v1 [1] was just to remove some global variables from
gt64xxx and piix4. During review it was noticed that the Malta board misses to
preserve the PCI IRQ levels during migration. Since the patch series offered an
easy fix v2 was born.

Furthermore, i8259[] was moved to PIIX4State in patch 1. This attribute seems
quite redundant to *isa to me. I therefore attempt to resolve it.

Tested with [2]:

  qemu-system-mips64 -M malta -kernel vmlinux-3.2.0-4-5kc-malta -hda \
  debian_wheezy_mips_standard.qcow2 -append "root=/dev/sda1 console=tty0"

It was possible to log in as root and `poweroff` the machine.
