Add support for the drm_panic module, which displays a message to the screen when a kernel panic occurs. v7 * Use drm_for_each_primary_visible_plane() v8: * Replace get_scanout_buffer() logic with drm_panic_set_buffer() (Thomas Zimmermann) v9: * Revert to using get_scanout_buffer() (Sima) * move get_scanout_buffer() to plane helper functions v12: * Use array for map and pitch in struct drm_scanout_buffer to support multi-planar format later.
