c20759506b video: tegra: nvmap: Add field to indicate hugetlbfs based memory 
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.

7c70fdd3f1 video: tegra: nvmap: Make function static. 
Fix for: Sparse defects

Sparse defect stated that "iovmm_debugfs_info" was not declared. Should it be static?
and symbol 'nvmap_max_handle_count' was not declared. Should it be static?

-Since iovmm_debugfs_info is only used in nvmap_debug.c, hence it can be
made static.
-Since nvmap_max_handle_count is only used in nvmap_handle.c, hence it can be
made static.
