drm/sun4i: Cleanup video/YUV source before enabling a layer This adds a dedicated function for cleaning the video and YUV source channel layer enable bits. This function is called first on layer atomic update to make sure that there are no leftover bits from previous plane configuration that were not cleaned until now. It fixes issues when alternating between video and YUV planes, where both bits would be set eventually, leading to broken plane display.
