pci: set PCI multi-function bit appropriately.

Set PCI multi-function bit according to multifunction property.
PCI address, devfn ,is exported to users as addr property,
so users can populate pci function(PCIDevice in qemu)
at arbitrary devfn.
It means each function(PCIDevice) don't know whether pci device...

pci: set multifunction property for normal device.

use pci_create_simple_multifunction() for normal device which sets
multifunction bit.
At the moment, only pc_piix.c and mips_malta.c uses multifunction
devices with piix3/4 pci-isa bridge.
And other boards don't populate those devices....

savevm: Add DeviceState param

When available, we'd like to be able to access the DeviceState

id strings.

should suffice. Actually, it is what happens when we reboot the machine,...

mips malta: Fix fdc regression and use qdev for i8042 setup

breaks MIPS Malta:

Tried to create isa device isa-fdc with no isa bus present

Fix this by creating an isa bus for piix4.
This change also requires some more qdev related changes...
