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....

pci: don't overwrite multi functio bit in pci header type.

Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared....

Fix overflow in i440fx_init()

The ram_size parameter can be larger than an int, so it may be truncated.
