Disable C/I based MS Power Control Loop by default
osmo-trx-uhd with a B200 has proven to provide bad (lower than usually considered good) C/I values due to high noise (even with band filters in place). Hence, default thresholds (gathered from literature on the topic) are too high and end up in bad algorithm output decisions. Furthermore, most users of Osmocom don't use it in densely populated areas, hence RXLEV based algorithm used when C/I based one is disabled is good enough. Let's disable C/I based one by default, and let advanced users which specific needs to enable and confiure thresholds specifically for their needs (hardware, cell surrounding conditions, etc.).
