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
