Guido Günther 1cc800e7aa ieee802154: Add trace events for rdev->ops
Enabling tracing via

 echo 1 > /sys/kernel/debug/tracing/events/cfg802154/enable

enables event tracing like

 iwpan dev wpan0 set pan_id 0xbeef
 cat /sys/kernel/debug/tracing/trace
 # tracer: nop

 # entries-in-buffer/entries-written: 2/2   #P:1
