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.
