drm-next-4.18-wip debug patch 3

Here's another debug patch to understand why the HDA codec refuses to power
down. I've removed some of the earlier debug printks as they're no longer
needed, so dmesg output should be shorter than before, still you may want to
add log_buf_len=10M to your command line to avoid losing messages.
