[PATCH] Fixes for the new Nvidia driver 352.21

[Luca Boccassi]

Dear Maintainer(s),

I am attaching a few patches, svn-diff'ed from top of the "346" SVN
development branch, revision 5355 (head), of the nvidia-graphics-drivers
repo. These fixes are needed in order to package the new 352.21 driver,
released recently by Nvidia. I built both x86_64 and i386 packages, and
I tested with a GTX 780, with both 4.0 and 3.16 kernel versions on
Jessie x86_64. I did not try to build the armhf packages. I found no
issues, everything seemed to work smoothly.

The patches fix the following:

- New IDs added to nv-readme.ids
- pci.ids and monitoring.conf are no longer shipped by Nvidia
- Refreshed the Quilt patches
- Added new symbols
- Conftest.sh looks for new functions: list_cut_position, phys_to_dma,
get_dma_ops, and new structs: dma_ops, noncoherent_swiotlb_dma_ops,
backing_dev_info. The DMA functions are arch-specific, so I did my best
to try and support x86, ARM, ARM64 and PPC (ARM64 and PPC in case it can
be useful in the future, since I read some interest on this mailing list
about adding support for those 2 archs). I believe the versions should
be correct, but please note that I only built the x86 packages.

Feel free to cherry-pick individual fixes from the diffs.

I hope this can be useful!

Kind regards,
Luca Boccassi
