tools/power turbostat: Make extensible via the --add parameter
Create the "--add" parameter. This can be used to teach an existing turbostat binary about any number of any type of counter. turbostat(8) details the syntax for --add. Signed-off-by: Len Brown <len.brown@intel.com>

.SS Options
Options can be specified with a single or double '-', and only as much of the option
name as necessary to disambiguate it from others is necessary. Note that options are case-sensitive.
+.PP
+\fB--add attributes\fP add column with counter having specified 'attributes'. The 'location' attribute is required, all others are optional.
+.nf
+ location: {\fBmsrDDD\fP | \fBmsr0xXXX\fP}
+ msrDDD is a decimal offset, eg. msr16

+ sample and print the counter for every cpu, core, or package.
+ default: cpu

+ 'raw' shows the MSR contents in hex.
+ 'delta' shows the difference in values during the measurement interval.
