apps/grgsm_trx: add baseband frequency shift feature
An ability to shift the baseband frequency would allow one to
run both base stations and (OsmocomBB-based) mobile stations on
any frequency (e.g. in 2.4 GHz WiFi band)!
This is achieved by adding a given frequency offset to the
result of "ARFCN -> RX/TX frequency" calculation.
Usage example:
grgsm_trx --freq-offset -500M
Both RX (Downlink) and TX (Uplink) frequencies will be shifted
by 500 MHz back, e.g. tuning request to ARFCN 105 would result
in tuning the radio to 456.0 MHz (instead of 956.0 MHz).
