perf tools: Allow to use cpuinfo on LoongArch
Define these macros so that the CPU name can be displayed when running
'perf report' and 'perf timechart'.
Committer notes:
No need to have:
if (strcasestr(buf, "Model Name")) {
strlcpy(cpu_m, &buf[13], 255);
break;
} else if (strcasestr(buf, "model name")) {
strlcpy(cpu_m, &buf[13], 255);
break;
}
As the point of strcasestr() is to be case insensitive to both the
haystack and the needle, so simplify the above to just:
if (strcasestr(buf, "model name")) {
strlcpy(cpu_m, &buf[13], 255);
break;
}
