As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers.
