Log:
  Add deprecation notice to mn(4)
  
  Sync serial (T1/E1) interfaces are largely irrelevant today and phk
  confirms this driver is unnecessary in review D23928.
  
  This leaves ce(4) and cp(4) in the tree.  They're likely not relevant
  either, but glebius contacted the manufacturer and those devices are
  still available for purchase.  At glebius' suggestion leave them in
  the tree as long as they do not impose a maintenace burden.
