Currently a void function can produce a warning:
  main.c:469: warning: contents before sections

This one is from arch/x86/kernel/cpu/sgx/main.c (which is not included
in any produced kernel documentation output).

Handle this by setting $in_doc_sect to 1 whenever any recognized
document section name is processed.

Fixes: f624adef3d0b ("kernel-doc: limit the "section header:" detection to a select few")
