atrf-gpio: added control commands; register read can now be masked

Browse Source 
- atrf-gpio.c (reg_op, usage): new command "delay" to add a 10 ms
  delay
- atrf-gpio.c (reg_op, usage): new command "frame" to write one
  byte to the frame buffer
- atrf-gpio.c (reg_op, usage): new command "reset" to reset the
  transceiver (via atrf_reset_rf)
- atrf-gpio.c (reg_op, usage): new command "slp_tr" to pulse SLP_TR
  (via atrf_slp_tr)
- atrf-gpio.c (reg_op, usage): register read can now be followed by a
  mask value
