PCI: Separate VF BAR updates from standard BAR updates

[ Upstream commit 6ffa2489c51da77564a0881a73765ea2169f955d ]

Previously pci_update_resource() used the same code path for updating
standard BARs and VF BARs in SR-IOV capabilities.

Split the VF BAR update into a new pci_iov_update_resource() internal
interface, which makes it simpler to compute the BAR address (we can get
rid of pci_resource_bar() and pci_iov_resource_bar()).

This patch:

  - Renames pci_update_resource() to pci_std_update_resource(),
  - Adds pci_iov_update_resource(),
  - Makes pci_update_resource() a wrapper that calls the appropriate one,

No functional change intended.
