    SR-IOV: deprecate supported_pci_vendor_devs

    Deprecate the supported_pci_vendor_devs option in order to reduce
    complexity for configuring SR-IOV. Currently, neutron validates the pci
    vendor and product id. However this check is already done by the
    nova-scheduler when it selects a suitable hypervisor. More precisely,
    the compute node validates this through the pci_passthrough_whitelist
    option in nova.conf. Therefore this check in neutron is redundant.

    This patch deprecates the supported_pci_vendor_devs in Newton release
    and updates the supported_pci_vendor_devs default to None.
    In case of None value the SR-IOV mechanism driver won't do
    any pci vendor validation. In case this option is set
    the SR-IOV mechanism driver will do the validaiton as it was
    before.
