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:

identifier helpers;
identifier func;

 static const struct drm_plane_helper_funcs helpers = {

 	.atomic_update = func,
