Subject: [PATCH 3/3] drm: Convert open yes/no strings to yesno()

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:

	@@
	expression b;
	@@

	- 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:
