Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

as a step towards this it will no longer be included in the

To prepare tinydrm/ for this add dependencies that

mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.
Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.
v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

The trouble here is that it does multiple atomic commits under one
drm_modeset_lock_all, which breaks the behind-the-scenes acquire
context magic that function pulls off. It's much better to have one
overall atomic commit. That we still have multiple atomic commits
prevents us from adding some pretty useful debug checks to the atomic
machinery.
Hence it is really a bad idea to call the legacy
drm_crtc_force_disable_all() function. There's 2 atomic drivers using
this still, nouveau and tinydrm. To fix this, introduce a new
drm_atomic_helper_shutdown() by extracting the code from i915.
While at it improve kernel-doc and catch future offenders by
sprinkling a WARN_ON into the legacy function. We should probably move
those into the legacy modeset helpers, too ...
v2: Make it compile on arm drivers too (Noralf).
