drm: Store new plane state in a variable for atomic_update and disable

Browse Source 
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,

 };

 	...,
 	.atomic_update = func,
	...,
 };
