net: mscc: ocelot: debugging print for statistics regions

Browse Source 
To make it easier to debug future issues with statistics counters not
getting aggregated properly into regions, like what happened in commit
6acc72a43eac ("net: mscc: ocelot: fix stats region batching"), add some
dev_dbg() prints which show the regions that were dynamically
determined.
