Code

dirtly made the atrf tools run with the new atusd board

Browse Source 
- lib/atusd.c: renamed CLK to SLP_TR
- lib/atusd.c (atusd_cycle, atusd_cycle, atusd_open, atusd_close):
  #ifdef'ed all uses of CLK and changed them to SLP_TR (along with the
  change in function)
- atrf-txrx/atrf-txrx.c (init_txrx): always use the crystal oscillator
