video: of: display_timing: Remove of_display_timings_exist() function
Since introduction of of_display_timings_exist() function in commit cc3f414cf2e40 ("video: add of helper for display timings/videomode") it didn't attract any users, and the function has no potential, because of_get_display_timings() covers its functionality and does more. Drop the unused exported function from the kernel. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
