Generic: Clean up output of AR8216 driver.

This patch is rather a cosmetic patch. It fixes the following issues:

 * Demote the unknown device message to debug level to not spam
   the log.
 * Fix the version print of the unknown device message.
 * Output the 'attach' message only when attaching as switch driver,
   not when attaching as phy driver.
 * Correctly return NET_RX_DROP when dropping packets.
