Fix kernel-doc formatting and add missing documentation for the members "barno" and "flags" of the struct pci_epf_bar, "msix_interrupts" of the struct pci_epf, "get_features" of the struct pci_epc_ops and "core_init_notifier" of the struct pci_epc_features. Thus, resolve build time warnings related to kernel-doc: include/linux/pci-epf.h:4: warning: This comment starts with '/**', but isn't a kernel-doc comment.
