tools/power turbostat: remove obsolete -M, -m, -C, -c options
The new --add option has replaced the -M, -m, -C, -c options Eg. -M 0x10 is now --add msr0x10,raw -m 0x10 is now --add msr0x10,raw,u32 -C 0x10 is now --add msr0x10,delta -c 0x10 is now --add msr0x10,delta,u32 The --add option can be repeated to add any number of counters, while the previous options were limited to adding one of each type. In addition, the --add option can accept a column label, and can also display a counter as a percentage of elapsed cycles. Eg. --add msr0x3fe,core,percent,MY_CC3 Signed-off-by: Len Brown <len.brown@intel.com>
