Downgrade gNB power limit LOG from "warning" to "debug"

Downgrade the UE power limited LOG from LOG_W to LOG_D. This is to avoid flooding stdout when UE in low coverage enters power limited state for a longer period of time. The same information can be inferred from the periodic UE print which also contains PH value (negative PH values indicate that the UE is power limited)

Also, correct some typos in PH calculation.

Closes #885 (closed)

OAI RAN-Container-Parent build (11799): failed (https://jenkins-oai.eurecom.fr/job/RAN-Container-Parent/11799/)

List of failing test stages:

• RAN-RF-Sim-Test-5G

Before demoting the LOG, are we sure we shouldn't be worried about that?

While trying to better understand the implication of the log, I realized there is a bug in PH calculation
