PCI: endpoint: Simplify epc->ops->set_bar()/pci_epc_set_bar()
Add barno and flags to struct epf_bar.
That way we can simplify epc->ops->set_bar()/pci_epc_set_bar()
by passing a struct *epf_bar instead of a whole lot of arguments.
This is needed so that epc->ops->set_bar() implementations can
modify BAR flags. Will be utilized in a succeeding patch.
