LoongArch: Replace seq_printf() with seq_puts() for simple strings

Browse source 
Fix warnings like: "Prefer seq_puts to seq_printf" by checkpatch.pl.

Replace seq_printf() calls with seq_puts() in show_cpuinfo() when
outputting simple constant strings without format specifiers.

This improves performance slightly as seq_puts() avoids parsing the
format string.
