linux/string_helpers.h provides a helper to return "yes"/"no"
strings. Replace the open coded versions with yesno(). The places were
identified with the following semantic patch:

- b ? "yes" : "no"
+ yesno(b)
Then the includes were added, so we include-what-we-use, and parenthesis
adjusted in drivers/gpu/drm/v3d/v3d_debugfs.c. After the conversion we
still see the same binary sizes:

Now it's possible to keep this on one line.

I believe it's fine to join back to have less LOCs (yes, it will be 83 or so,
but I believe in these cases it's very much okay).
now that we are converting to str_yes_no(), we will have a few more
chars. Some maintainers may be more strict on the 80 or 100 chars. I
will assume whatever is in the code base is the preferred form.
