media: aspeed-video: Fix memory leaks in aspeed_video_probe

In the implementation of aspeed_video_probe() the allocated memory for
video should be released if either devm_ioremap_resource()
or aspeed_video_init() or aspeed_video_setup_video() fails. Replace
kzalloc() with devm_kzalloc to avoid explicit release for video.
