[PATCH master] firmware: use portable newline escape

[Ahmad Fatoum]

We want to print `\n' literally into the *.gen.S file, so gas turns it
into a literal new line character. Depending on shell, the current
scheme might work, but let's play it safe and use single quotes. This
fixes a cosmetic issue of non-escaped `\n' making it into the missing
section on NixOS, which leads to slightly garbled output when firmware
is missing.
