Fix kernel-doc formatting and add missing documentation for the "node" parameter of the of_get_pci_domain_nr() and of_pci_get_max_link_speed() functions, and resolve build time warnings related to kernel-doc: drivers/pci/of.c:202: warning: expecting prototype for This function will try to obtain the host bridge domain number by().
