drm/simple-kms-helper: Plumb plane state to the enable hook

Browse source 
tinydrm enable hook wants to play around with the new fb in
.atomic_enable(), thus we'll need access to the plane state.

Performed with coccinelle:
@r1@
identifier F =~ ".*enable$";
identifier P, CS;
@@
F(
	struct drm_simple_display_pipe *P
	,struct drm_crtc_state *CS
+	,struct drm_plane_state *plane_state
	)
{
...
}

@@
struct drm_simple_display_pipe *P;
expression E;
@@
{
+ struct drm_plane *plane;
...
+ plane = &P->plane;
P->funcs->enable(P
		,E
+		,plane->state
	);
...
}

@@
identifier P, CS;
@@
struct drm_simple_display_pipe_funcs {
...
        void (*enable)(struct drm_simple_display_pipe *P
	     		,struct drm_crtc_state *CS
+			,struct drm_plane_state *plane_state
		);
...
};
