net: dsa/phy: remove temporary bring-up debug instrumentation

Drop temporary debug messages that were added while debugging DSA mux/phylink
lifecycle and AS21xxx bring-up.

- remove verbose `pr_info`/`dev_info`/`pr_debug` progress traces in DSA setup
  and mxl862xx paths
- remove AS21xxx debug chatter (`aeon_dbg` callsites and noisy init/exit prints)
- keep actionable warning/error logs for real failures

This is a log-noise cleanup only, with no functional behavior changes.
