Refactor the last nvgpu_vm functions from the mm_gk20a.c code. This removes some usages of dma_buf from the mm_gk20a.c code, too, which helps make mm_gk20a.c less Linux specific. Also delete some header files that are no longer necessary in gk20a/mm_gk20a.c which are Linux specific. The mm_gk20a.c code is now quite close to being Linux free.
