This fixes the following build error

drivers/gpu/drm/kmb/kmb_plane.c: In function 'kmb_plane_atomic_disable':
drivers/gpu/drm/kmb/kmb_plane.c:165:34: error: array subscript 3 is above array bounds of 'struct layer_status[2]' [-Werror=array-bounds]
  165 |                 kmb->plane_status[plane_id].ctrl =
  LCD_CTRL_GL2_ENABLE;
