tools/power/turbostat: add option to count SMIs, re-name some options
Counting SMIs is popular, so add a dedicated "-s" option to do it, and juggle some of the other option letters. -S is now system summary (was -s) -c is 32 bit counter (was -d) -C is 64-bit counter (was -D) -p is 1st thread in core (was -c) -P is 1st thread in package (was -p) bump the minor version number Signed-off-by: Len Brown <len.brown@intel.com>
