Fixes a regression caused by a stupid thinko from "disp/sor/gf119: both
links use the same training register".

git://anongit.freedesktop.org/drm-intel into drm-next
I recovered dri-devel backlog from my vacation, more misc stuff:
- of_put_node fixes from Peter Chen (not all yet)
- more patches from Gustavo to use kms-native drm_crtc_vblank_* funcs
- docs sphinxification from Lukas Wunner
- bunch of fixes all over from Dan Carpenter
- more follow up work from Chris register/unregister rework in various
places
- vgem dma-buf export (for writing testcases)
- small things all over from tons of different people

Use shiny new drm_crtc_force_disable() instead of open coding the same.
No functional change intended.

nouveau leaks a runtime pm ref if at least one CRTC is enabled on
unload. The ref is taken by nouveau_crtc_set_config() and held as long
as a CRTC is in use.
nv04_display_destroy() should solve this by turning off all CRTCs, but
(1) nv50_display_destroy() doesn't do the same and
(2) it's broken since commit d6bf2f370703 ("drm/nouveau: run mode_config
destructor before destroying internal display state") because the
crtc structs are torn down by drm_mode_config_cleanup() before being
turned off. Also, there's no locking.
Move the code to turn off all CRTCs from nv04_display_destroy() to
nouveau_display_destroy() so that it's called for both nv04 and nv50
and before drm_mode_config_cleanup(). Use drm_crtc_force_disable_all()
helper to save on code and have proper locking.

The PCI core calls pm_runtime_forbid() on device probe in pci_pm_init(),
making this the default state when nouveau is loaded. nouveau_drm_load()
therefore calls pm_runtime_allow(), but there's no pm_runtime_forbid()
in nouveau_drm_unload() to balance it. Add it so that we leave the
device in the same state that we found it.
This isn't a bug, it's just good housekeeping. When nouveau is first
loaded with runpm=1, then unloaded and loaded again with runpm=0,
pm_runtime_forbid() will be called from nouveau_pmops_runtime_idle() or
nouveau_pmops_runtime_suspend(), so the behaviour is correct. The nvidia
blob doesn't use runtime pm, but if it ever does, this commit avoids
that it has to clean up behind nouveau.

nouveau_drm_load() calls pm_runtime_put() if nouveau_runtime_pm != 0,
but nouveau_drm_unload() calls pm_runtime_get_sync() unconditionally.
We therefore leak a runtime pm ref whenever nouveau is loaded with
runpm=0 and then unloaded. The GPU will subsequently never runtime
suspend even if nouveau is loaded again with runpm=1.
Fix by taking the runtime pm ref under the same condition that it was
released on driver load.

Here's an initial drm-next pull for nouveau 4.8, highlights:
- GK20A/GM20B volt and clock improvements.
- Initial support for GP100/GP104 GPUs, GP104 will not yet support
acceleration due to NVIDIA having not released firmware for them as of yet.

This flag's only remaining function is to ignore the uncached flag for
BOs on coherent architectures.
However the reason for allocating an object uncache on a non-coherent
architecture (namely because the cost of doing explicit flushes/
invalidations is higher than the benefit of caching the data because
accesses are few and far between) should also apply on architectures for
which coherency is maintained implicitly. Thus allocate coherent objects
as uncached on all architectures.

TTM-allocated coherent objects were populated using the DMA API and
accessed using the mapping it returned to workaround coherency
issues. These issues seem to have been solved, thus remove this extra
case to handle and use the regular kernel mapping functions.

Due to the GPU preventing us from touching NV_PLTCG_LTCS_LTSS_CBC_BASE,
we cannot provide CBC/ZBC support without signed PMU firmware to handle
the task for us...

GP100 still supports the previous generations' page table layout, which
we will temporarily make use of here.
Proper support for the new MMU layout requires some rework to the common
MMU code, which is in progress.
