Tested with [1]:
qemu-system-mipsel -M malta -kernel vmlinux-3.2.0-4-4kc-malta -hda \
debian_wheezy_mipsel_standard.qcow2 -append "root=/dev/sda1 console=tty0"
It was possible to log in as root and `poweroff` the machine.

v4:
As suggested by BALATON Zoltan, gt64120_register() is now resolved by
sysbus_create_simple() etc. This also fixes the nitpick pointed out by
Philippe.
v3:
The migration bug now gets fixed in gt64xxx_pci before any cleanup. As
suggested by PMM the patch is based on commit e735b55a8c11.
The code movement patch now moves the already fixed code. I might be a bit
too conservative here by removing Philippe's Reviewed-By tag.
As suggested by BALATON Zoltan, the redundant i8259[] attribute is now
resolved immediately after the code movement. As a side effect, it also
removes moved code which doesn't adhere to the coding style (local loop
variable).
To address BALATON Zoltan's comment and to reduce the number of required
Reviewed-By's, only piix4_set_irq() is modified to expect own DeviceState
paremeter. Up to v2, all remaining set_irq() functions were changed this
way.
The patch resolving piix4's singleton variable got split into two patches:
One which resolves the singleton variable and one which replaces magic
constants. The split patches should be more comprehensible.
Suggested by BALATON Zoltan, I took a chance to resolve gt64120_register(),
a method akin to the legacy init functions we're trying to get rid of.
v2:
isa/piix4: Fix PCI IRQ levels to be preserved in VMState
isa/piix4: Resolve redundant i8259[] attribute
Bernhard Beschow (7):
hw/mips/gt64xxx_pci: Fix PCI IRQ levels to be preserved during
migration
malta: Move PCI interrupt handling from gt64xxx_pci to piix4
hw/isa/piix4: Resolve redundant i8259[] attribute
hw/isa/piix4: Pass PIIX4State as opaque parameter for piix4_set_irq()
hw/isa/piix4: Resolve global instance variable
hw/isa/piix4: Replace some magic IRQ constants
hw/mips/gt64xxx_pci: Resolve gt64120_register()
