media: venus: venc: configure entropy mode

Browse Source 
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.
