Subject: [PATCH] This patch replaces all the instances of dev_info with drm_info macro

When a driver has multiple instances it is necessary to differentiate
between them in the logs. This was done with dev_info/warn/err since
DRM_INFO/WARN/ERROR don't do this. We now have drm_info/warn/err for
printing the relevant debug messages. Hence, this patch uses
drm_* macros to achieve drm-formatted logging

Well first of all patches for radeon should have a drm/radeon prefix in
its subject line.

Then I don't think this patch makes sense since this is about the
hardware support of the module and not even remotely drm related.

So we most likely don't want the drm-formating here in the first place.

Regards,
Christian.
