tools/power turbostat: print more turbo-limit information
The "turbo-limit" is the maximum opportunistic processor speed, assuming no electrical or thermal constraints. For a given processor, the turbo-limit varies, depending on the number of active cores. Generally, there is more opportunity when fewer cores are active. Under the "-v" verbose option, turbostat would print the turbo-limits for the four cases of 1 to 4 cores active. Expand that capability to cover the cases of turbo opportunities with up to 16 cores active. Note that not all hardware platforms supply this information, and that sometimes a valid limit may be specified for a core which is not actually present.
