video: driver: tune dcvs and batching buffer count

Browse Source 
[1] add dcvs cushion buffers, only if core supports dcvs
[2] update buffer_count for dcvs & batching for priority
    static control.
[3] add max_fps & max_mbpf checks to disable decode_batching.
[4] add low_latency check in msm_vidc_allow_dcvs api.
