Christian Lamparter dce072580e p54: more SoftLED updates 
This patch hopefully finishes the SoftLED code:
- It adds two more LEDs (rx and radio).
  (the FW claims it can support up to 16 LEDs,
   but I doubt that any vendor put more than 4 on a board)
- update the LEDs in a _delayed_ workqueue.
  No one reported any more crashes.
  (see: "PATCH] p54: fix race condition in memory management")
  So we can stop burning the mm code.
