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 start convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_async_check and
atomic_async_update.

The conversion was done using the coccinelle script below, built tested on
all the drivers.

Most drivers call the argument to the plane atomic_check hook simply
state, which is going to conflict with the global atomic state in a
later rework. Let's rename it to new_plane_state (or new_state depending
on the convention used in the driver).

This was done using the coccinelle script below, and built tested:

identifier helpers;
identifier func;

 static const struct drm_plane_helper_funcs helpers = {
 	.atomic_check = func,

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 start convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.

The conversion was done using the coccinelle script below plus some
manual changes for vmwgfx, built tested on all the drivers.

Now that atomic_check takes the global atomic state as a parameter, we
don't need to go through the pointer in the plane state.

This was done using the following coccinelle script:

That function is using old_state for plane->state:
