From: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx>
Some times people send their dmesg log for debugging, and one common
task is to check the modesetting line to catch which DCN/DCE we need to
debug. This commit introduces a simple conversion from the DCN/DCE
version to a string shown in the dmesg log.
