Subject: [PATCH 3/3] LoongArch: Relocate the seq_file declaration to the correct place

The seq_file structure only needs to be declared in a header file
when CONFIG_SMP is enabled. Therefore, it clearly belongs in smp.h,
which, however, does not declare it. Instead, cpuinfo.h inappropriately
declares this structure, fortuitously allowing the code to function.
