[FFmpeg-cvslog] avfilter/x86/vf_yadif: Remove obsolete MMXEXT functions

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Mon Jun 13 08:34:13 2022 +0200| [4d7128be9a31c7bf6cb79436711ded3cc9767fe8] | committer: Andreas Rheinhardt

avfilter/x86/vf_yadif: Remove obsolete MMXEXT functions

The only system which benefit from these are truely ancient
32bit x86s as all other systems use at least the SSE2 versions
(this includes all x64 cpus (which is why this code is restricted
to x86-32)).
