Subject: [PATCH 0/2] PCI: VF resizable BAR

For regular BAR, drivers can use pci_resize_resource to resize it to the desired
size provided that it is supported by the hardware, which the driver can query
using pci_rebar_get_possible_sizes.
This series expands the API to work with IOV BAR as well.

Thanks!
