layer1: Fixed power measurement, adding ARFCN wrapping 

Power measurement returned the first measurement result twice, now it is
returned only once.

Wrapping of ARFCN allows to measure the E-band en block. After measuring the
ARFCN 1023, the ARFCN wraps to 0. Special flags like ARFCN_UPLINK or
ARFCN_PCS are preserved while wrapping.
