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.)
