Remove unnecessary Lime calibration step from Soapy implementation 

When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.
