Rx band filter response compensation (GSM)

Prerequisites
Rx calibration must be performed before the Rx band filter response compensation.
Context
On each GSM Rx band, there is a band filter in front of the RF ASIC front end. The amplitude ripple caused by
these filters causes ripple to the RSSI measurement, and therefore calibration is needed.
