Subject: [PATCH] LoongArch: Make lscpu show "Model name" and "CPU family"

When update the latest kernel on LoongArch, and then use lscpu command
to show cpuinfo, we can not see "Model name" and "CPU family", this is
because there are no matched patterns in /proc/cpuinfo, use small letter
of "Model Name" and "CPU Family" in show_cpuinfo() to fix it.

Here is the related code of lscpu:

static const struct cpuinfo_pattern type_patterns[] =
{
...
        DEF_PAT_CPUTYPE( "cpu family",          PAT_FAMILY,     family),
...
        DEF_PAT_CPUTYPE( "model name",          PAT_MODEL_NAME, modelname),
...
};
