PCI: Remove pci_resource_bar() and pci_iov_resource_bar()
[ Upstream commit 286c2378aaccc7343ebf17ec6cd86567659caf70 ]
pci_std_update_resource() only deals with standard BARs, so we don't have
to worry about the complications of VF BARs in an SR-IOV capability.
Compute the BAR address inline and remove pci_resource_bar(). That makes
pci_iov_resource_bar() unused, so remove that as well.
