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.
