Add the following changes to build dgpu sources for kernels after 4.14:
1. tegra_alloc_fd is defined by downstream tegra mc driver built with
the flag CONFIG_NV_TEGRA_MC, hence make the nvgpu config
NVGPU_USE_TEGRA_ALLOC_FD dependent on it.
2. dma_buf_ops.map_atomic is removed in kernel version 4.17.
3. gk20a_vidbuf_ops.set_drvdata and .get_drvdata are to be set
under the config CONFIG_NVGPU_DMABUF_HAS_DRVDATA

Rule 2.2 doesn't allow unused variable assignments. The reason is
presence of unused variable assignments may indicate error in program's
logic.
Rule 21.x doesn't allow reserved identifier or macro names starting with
'_' to be reused or defined.

There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.
Much of this is fairly straightforward copy/paste and updates to the
HAL init files.
The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.

1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>
2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

Rename os/linux/vidmem.c to os/linux/dmabuf_vidmem.c. The code is
mainly dealing with interfacing with Linux dmabuf framework and its
responsibilities got confused with common/mm/vidmem.c.
Also move the header include/nvgpu/linux/vidmem.h to
os/linux/dmabuf_vidmem.h. It does not expose any interface to outside
Linux code.
