video: tegra: nvmap: Add field to indicate hugetlbfs based memory

Browse Source 
Hugetlbfs memory handles are shown under the IOVMM debugfs as the memory
comes from the system memory and not from any carveout. But it is
causing confusion among the customers. Hence add a field to indicate if
the buffer was allocated from hugetlbfs or not.
