Subject: [PATCH 2/3] drm/arm/komeda: Move pipeline prints to after the entire pipeline has been enabled

The komeda driver prints a pretty verbose log in komeda_pipeline_dump()
detailing the components of each of the two pipelines. This gets printed
multiple times during boot as komeda EPROBE_DEFERs waiting for the
remote bridge drivers to come up. Move this log to after this has
happened indicating that the printed pipeline is actually completely up.
