drm/amd/display: switch DC over to the new DRM logging macros

For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.

We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.
