science/sigrok-firmware-fx2lafw: Update to version 0.1.6.
Changes: 0.1.6 (2018-01-26)
- Fix an issue with FX2 based logic analyzers that could cause non-working and/or prematurely aborted acquisitions (bug #655).
- FX2 based logic analyzers will now toggle pin PA1 during acquisition, and keep it high while idle. On fx2grok-tiny and fx2grok-flat devices there's a LED connected to PA1. Thus, those devices will visually indicate whether a firmware has been uploaded (LED will light up and stay like that while the device is idle). During any acquisition the LED will blink.
- Refactor the oscilloscope code to avoid duplication (bug #984).
- Fix a 'make distclean' error.
- Fix a compiler warning with recent sdcc versions (e.g. v3.6.9).
