tools/: rearranged cwtest/atrf-path to be more clear about reset and do re-init

Browse Source 
- include/cwtest.h (cw_test_needs_reset), lib/cwtest.c
  (cw_test_needs_reset): new function to indicate all cases where the
  transceiver needs to be reset (instead of using SLP_TR)
- lib/cwtest.c (cw_test_end): use cw_test_needs_reset instead of
  open-coding the decision
- lib/cwtest.c (enter_test_mode_230, start_test_mode_231): always wait
  for the PLL to lock. Contrary to the assumption in the previous
  commit, we should always see this interrupt.
- atrf-path/atrf-path.c (sample): initialize the transceiver if we had
  to reset it
- atrf-path/atrf-path.c (sample), atrf-path/atrf-path.c (do_half_sweep):
  moved the tTR19 delay to "sweep", so that all branches share it and it
  is taken only once
