media: venus: venc: configure entropy mode
H264 entropy mode can be selected via V4L2 API but is eventually not
applied. Configure encoder with selected mode, CALVC (def) or CABAC.
Note that hw/firmware also expects a CABAC model configuration which
currently doesn't have existing V4L2 API control. For now, use model_0
which seems always supported and so the default one.
