video: driver: Add support dynamic low latency for decoder

Browse Source 
Latency property is set to firmware during streamon output port,
if set as part of initial configuration by client.
During runtime, the property is set as and when configured by
client.

1. Make the latency property dynamic for decoder.
2. For encoder, the same gets set to firmware with regular
   v4l2 set properties.
3. For decoder, set the property explicitly during streamon
   output port.
