Subject: [PATCH 2/2] tools/power turbostat: bugfix: fix several invalid parameters

dump_cstate_pstate_config_info is invoked with no parameters,
which might cause this function to misjudge the processor family
and model. Fix this by passing family and model to it.

Besides, fix the compiling warning caused by missing type declaration
in dump_cstate_pstate_config_info, get_tdp and perf_limit_reasons_probe:

turbostat.c: In function ‘dump_cstate_pstate_config_info’:
turbostat.c:1973:1: warning: type of ‘family’ defaults to ‘int’ [-Wimplicit-int]
 dump_cstate_pstate_config_info(family, model)
 ^
turbostat.c:1973:1: warning: type of ‘model’ defaults to ‘int’ [-Wimplicit-int]
turbostat.c: In function ‘get_tdp’:
turbostat.c:2145:8: warning: type of ‘model’ defaults to ‘int’ [-Wimplicit-int]
 double get_tdp(model)
        ^
turbostat.c: In function ‘perf_limit_reasons_probe’:
turbostat.c:2259:6: warning: type of ‘family’ defaults to ‘int’ [-Wimplicit-int]
 void perf_limit_reasons_probe(family, model)
      ^
turbostat.c:2259:6: warning: type of ‘model’ defaults to ‘int’ [-Wimplicit-int]
