cpumask: add show cpu map functions
* Add cpu_sysdev_class functions to display the following maps with cpulist_scnprintf(). cpu_online_map cpu_present_map cpu_possible_map * Small change to include/linux/sysdev.h to allow the attribute name and label to be different (to avoid collision with the "attr_online" entry for bringing cpus on- and off-line.)
