pci/multi function bit: fix vt82c686.c.
The file, vt82c686.c, was added after the change set ofb80d4a9887fa4b6cc63f8c3a13ab2a45054d3e5c andfecb93c45c749a4c994d8d12bdee17ce2012de9eare created, but before the patch series was commit.So similar fix is needed to vt82c686.c....

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 setsmultifunction bit.At the moment, only pc_piix.c and mips_malta.c uses multifunctiondevices 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() setsappropriately is lost.Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zerowhich is already zero cleared....
pci: insert assert that auto-assigned-address function is single function device.
Auto-assigned-address pci function (passing devfn = -1) is alwayssingle function.This patch adds assert() to guarantee that auto-assigned-address functionis always single function device at function = 0....
