HW encoding and decoding speed

Hi,
Enabling the properties shall have latency enhancement:

// nvv4l2h264enc (poc-type=2)
  maxperf-enable      : Enable or Disable Max Performance mode
                        flags: readable, writable, changeable only in NULL or READY state
                        Boolean. Default: false
  poc-type            : Set Picture Order Count type value
                        flags: readable, writable, changeable only in NULL or READY state
                        Unsigned Integer. Range: 0 - 2 Default: 0
// nvv4l2decoder
  disable-dpb         : Set to disable DPB buffer for low latency
                        flags: readable, writable
                        Boolean. Default: false
  enable-max-performance: Set to enable max performance
                        flags: readable, writable
