drm/panel: Don't store+check prepared/enabled for simple cases
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. This pile of panel drivers appears to be simple to handle. Based on code inspection they seemed to be using the prepared/enabled state simply for double-checking that nothing else in the kernel called them inconsistently. Now that the core drm_panel is doing the double checking (and warning) it should be very clear that these devices don't need their own double-check.
