Use the postprocessor functions introduced by Hantro G2/VP9 codec series and remove duplicated buffer management. This allow Hantro G2/HEVC to produce NV12_4L4 and NV12. Fluster HEVC score is 77/147 which equal to previous score. Beauty, Jockey and ShakeNDry bitstreams from UVG (http://ultravideo.fi/) set have also been tested.
