Right now the decoder maintains two separate lists for supported pixel formats and frame sizes. Getting the supported frame sizes for the current set format is a bit convoluted, requiring a search through the separate frame size list. The frame sizes are used to clamp and align requested resolutions. Instead, the frame size structure could be embedded inside the pixel format structure. Getting one also gets the other. And since the the driver already keeps pointers to the current set format, getting the frame sizes becomes straightforward. Do just that. Move v4l2_frmsize_stepwise inside mtk_video_fmt, and get rid of mtk_codec_framesizes.
