tools/lib/cwtest.c (cw_test_end): try "quick reset" on AT86RF231
The transceiver reset takes quite a while. It seems that also going into sleep mode has the effect of stopping cw test mode and it's much faster. This has only been tried on the AT86RF231. For AT86RF230, we therefore still use the reset. Performance improvement: Measurement: atrf-path sweep time in GUI mode, averaging over 10 samples. Running on PC with remote ATBEN transceivers. before 7.36-7.68 s after 2.08 s (27-28% of previous time)
