drm: Store new plane state in a variable for atomic_update and disable
In order to store the new plane state in a subsequent helper, let's move
the plane->state dereferences into a variable.
This was done using the following coccinelle script, plus some hand
changes for vmwgfx:
@ 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,
...,
};
