PCI/IOV: Allow IOV resources to be resized in pci_resize_resource()
Similar to regular resizable BARs, VF BARs can also be resized.
The capability layout is the same as PCI_EXT_CAP_ID_REBAR, which means we
can reuse most of the implementation, the only difference being resource
size calculation (which is multiplied by total VFs) and memory decoding
(which is controlled by a separate VF MSE field in SR-IOV cap).
Extend the pci_resize_resource() function to accept IOV resources.
See PCIe r6.2, sec 7.8.7.
