According to BSP library source, H264 neighbour info buffer size needs to be 32 kiB for H6. This is similar to H265 decoding, which also needs double buffer size in comparison to older Cedrus core generations. Increase buffer size to cover H6 needs. Since increase is not that big in absolute numbers, it doesn't make sense to complicate logic for older generations. Issue was discovered using iommu and cross checked with BSP library source.
