missing space before '*/'

If all three models mt8173, mt8183 and mt8192 support the same formats then
we should probably not name the structs according to one of the models, so maybe:

s/mtk_video_formats_capture_mt8183/mtk_video_formats_capture/
s/mtk_video_formats_output_mt8173/mtk_video_formats_output/

or some other naming

Thanks,
Dafna
