Collectd 5.9.0 changed the data structure of the cpufreq plugin: CPU cores are now handled as separate plugin instances. There are also new data items per core: * time spent at each frequency * amount of frequency transitions Enable these new data items, but initially hide them behind a new config option "ExtraItems" (default: disabled), as the amount of graphs in multi-core systems could be rather large. Note that the frequencies are not (yet) sorted, so the information value of the time-spent graph is semi-random. Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi>
