Description
As seen on my limenet-mico3 while running some stability test, lot's of these messages may swamp the stderr log at some point. Let's try to avoid printing each time or completely dropping the log line, and use a rate_ctr instead.

Good idea about adding stats for this.
But please do not remove this log output - it's useful when debugging. Just move it to DEBUG level.

I think it's not just clipping. There are many situations (also seen in SYS#5014) which
are potentially happening at every burst:
are potentially happening at every burst:
- empty burst (no energy in the channel)
- clipping detected
- no RACH or NB detected
We should have counter for (at least) all of these.
Given that we may have different radio carrier (ARFCN) and TS, the counters should
exist at least on a per-carrier basis, if not even on a per-TS basis.
