msm: vidc: Restrict dynamic low latency for h264 and hevc

Browse source 
In existing approach, dynamic low latency i.e low latency hint
is restricted via specific low latency components in userspace.
This change adds one more checkpoint to ensure that video
firmware is configured for low latency only for desired codecs.
