The expectation is that the struct drm_device based logging helpers get
passed an actual struct drm_device pointer rather than some random
struct pointer where you can dereference the ->dev member.

Convert drm_err(hdmi, ...) to dev_err(hdmi->dev, ...). This matches
current usage, but drops "[drm] *ERROR*" prefix from logging.

Looks like it's possible to hunt down the struct drm_device in most of
these cases, if that's desired. This was the simplest change.
