tools/power/x86/intel-speed-select: Output success/failed for command output

Command output has confusing data, returning "0" on success.  For example

|# ./intel-speed-select -c 14 turbo-freq enable
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
 package-1
   die-0
     cpu-14
       turbo-freq
         enable:0

To avoid confusion change the command output to 'success' or 'failed'.

v2: Remove help output line.
