120 MHz daughterboard support, Integer-N tuning, ADF435x code consolidation

* Added support for new CBX-120, SBX-120, and WBX-120 daughterboards
* Added implementation of Integer-N tuning for all CBX, SBX, and WBX daughterboards
* Added --int-n option to examples to show how to use Integer-N tuning API
* Removed duplicate ADF4350/ADF4351 code and moved it to common/adf435x_common.cpp
