[Intel-gfx] [PATCH 1/3] lib/string_helpers: Consolidate yesno() implementation

There are a few implementations of yesno() in the tree. Consolidate them
in include/linux/string_helpers.h. Quite a few users of open coded
yesno() could later be converted to the new function:
$ git grep '?\s*"yes"\s*' | wc -l
286
$ git grep '?\s*"no"\s*' | wc -l
20
The inlined function should keep the const strings local to each
compilation unit, the same way it's now, thus not changing the current
behavior.
