Set correct master clock rate for N320

changed milestone to %REVIEW_CAN_START

added BUILD-ONLY label

requested review from @florian.kaltenberger

@florian.kaltenberger as I already wrote on slack: I get the following error roughly every second run:

terminate called after throwing an instance of 'uhd::runtime_error'
  what():  RuntimeError: rx xport timed out getting a response from mgmt_portal

I am not sure whether this is an issue with running the USRP over Fibrolan, the N320, or the management address configuration (which I think is correct). Maybe we can treat this in the context of this MR?
