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:

@ plane_atomic_func @
identifier helpers;
identifier func;

(
 static const struct drm_plane_helper_funcs helpers = {
 	...,
 	.atomic_disable = func,

 };
|
 static const struct drm_plane_helper_funcs helpers = {
 	...,
 	.atomic_update = func,
	...,
 };
)

@ adds_new_state @
identifier plane_atomic_func.func;
identifier plane, state;
identifier new_state;
