This migrates the common DMA code (os agnostic) to the
common directory. This new unit will be the common DMA
allocator that lets users allocate SYSMEM, VIDMEM, or
either. Other units will be responsible for actually
handling the mechanics of allocating VIDMEM or SYSMEM.
Also update the names of the DMA related files so that
tmake doesn't complain about duplicate C file names. To
do this call the common DMA file dma.c and prepend the
OS to the other DMA files. So now we have:
common/mm/dma.c
os/posix/posix-dma.c
os/linux/linux-dma.c

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.

In nvgpu_dma_alloc_flags_vid_at(), we check pending bytes of vidmem which are
yet to be cleared by reading g->mm.vidmem.bytes_pending.atomic_var
If there is something to be cleared we return EAGAIN otherwise we return ENOMEM
But to store above variable we use "int before_pending" which evaluates to zero
for sizes like 4GB and we end up returning ENOMEM instead of EAGAIN
Fix this by declaring before_pending variable as u64

Add a wrapper function nvgpu_dma_alloc_vid_at() for performing vidmem
allocation at a specific address without needing to pass any flags.

Move all Linux source code files to drivers/gpu/nvgpu/os/linux from
drivers/gpu/nvgpu/common/linux. This changes the meaning of common
to be OS independent.
