connected to PFIFO.

Marcin Slusarz a4cea27b69 drm/nouveau: share fence structures between nv10+ and nv50 implementations
We already rely on them having the same fields and layout.

Marcin Slusarz f20ebd034e drm/nv17-50: restore fence buffer on resume
Since commit 5e120f6e4b "drm/nouveau/fence:
convert to exec engine, and improve channel sync" nouveau fence sync
implementation for nv17-50 and nvc0+ started to rely on state of fence buffer
left by previous sync operation. But as pinned bo's (where fence state is
stored) are not saved+restored across suspend/resume, we need to do it
manually.

nvc0+ was fixed by commit d6ba6d215a
"drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

Marcin Slusarz 04c8c21085 drm/nouveau: unpin various bo's before destroying
These objects leak VRAM - but only on module unload.

Ben Skeggs ebb945a94b drm/nouveau: port all engines to new engine module format
This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination.  It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.

Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.

v2: Marcin Slusarz <marcin.slusarz@gmail.com>
- fix find/replace bug in license header

v3: Ben Skeggs <bskeggs@redhat.com>
- bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and
  left no space for kernel's requirements during GEM pushbuf submission.
- fix duplicate assignments noticed by clang

v4: Marcin Slusarz <marcin.slusarz@gmail.com>
- add sparse annotations to nv04_fifo_pause/nv04_fifo_start
- use ioread32_native/iowrite32_native for fifo control registers

v5: Ben Skeggs <bskeggs@redhat.com>
- rebase on v3.6-rc4, modified to keep copy engine fix intact
- nv10/fence: unmap fence bo before destroying
- fixed fermi regression when using nvidia gr fuc
- fixed typo in supported dma_mask checking

Ben Skeggs f589be88ca drm/nouveau/pageflip: kick flip handling out of engsw and into fence
This is all very much a policy thing, and hence will not belong in SW
after the rework.

engsw now only handles receiving the event to say "can flip now" and makes
a callback to perform the actual work.
