PCI: Add VPD function 0 quirk for Intel Ethernet devices
[ Upstream commit 7aa6ca4d39edf01f997b9e02cf6d2fdeb224f351 ]
Set the PCI_DEV_FLAGS_VPD_REF_F0 flag on all Intel Ethernet device
functions other than function 0, so that on multi-function devices, we will
always read VPD from function 0 instead of from the other functions.
