[FFmpeg-devel,3/5] avcodec/libsvtav1: remove the unsupported color format and profile

From: Limin Wang <lance.lmwang@gmail.com>

If you enable YUV422 or YUV444, SVT-AV1 library will report "only support 420 now" error,
so it's better to remove the unsupported code.

... not that you can even get to that message at the moment, because the encoder wrapper only accepts YUV420P and YUV420P10 anyway.

Sure, LGTM.

Sorry, my commit message isn't clear, in fact, I add the code to enable YUV422
and YUV444, but by the testing result, it'll failed, so I remove the unsupported code.
