[ Upstream commit 08a83828825cbf3bc2c9f582a4cd4da9f40c77d6 ]

Will return -EINVAL using standard framework api when test stateless
decoder with cmd VIDIOC_(TRY)DECODER_CMD. Disable them to adjust v4l2
compliance test for user driver(GStreamer/Chrome) won't use decoder cmd.

Fixes: 8cdc3794b2e3 ("media: mtk-vcodec: vdec: support stateless API")
