Subject: [MTX-4445] mPower R.6.0.X: MTCAP3: LNA7D - cellular radio support
 GP-1548 setRxDiversity command moved to common class for Quectel radios -
 QuectelRadio.cpp. Add LNA7D radio support. LNA7D radio supports only 3g and
 4g network modes. Add new command for enabling/disabling diversity. Retained
 backward compatibility with the old diversity command.
