drm: Use state helper instead of the plane state pointer

Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.

Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.

This was made using the coccinelle script below:

static const struct drm_plane_helper_funcs helpers = {

drm/atomic: Pass the full state to planes atomic disable and update

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

drm: Rename plane->state variables in atomic update and disable

Some drivers are storing the plane->state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.

In order to ease subsequent reworks and to avoid confusing or
inconsistent names, let's rename those variables to new_state.

This was done using the following coccinelle script, plus some manual

drm/atomic: Pass the full state to CRTC atomic enable/disable

If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.

In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.

drm/hisilicon: Code refactoring for hibmc_drv_de

The memory used to be allocated with devres helpers and released
automatically. In rare circumstances, the memory's release could
have happened before the DRM device got released, which would have
caused memory corruption of some kind. Now we're embedding the data
structures in struct hibmc_drm_private. The whole release problem
has been resolved, because struct hibmc_drm_private is allocated
with drmm_kzalloc and always released with the DRM device.

drm: Split out drm_probe_helper.h

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.

drm: Nuke fb->bits_per_pixel

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.
