transceiver, uhd: runtime check for setting master clock rate
Before setting the master clock rate, make sure that the
device is capable of being set. For now, assume that devices
that operate with default clock rates above 64 MHz,
specifically USRP2/N200/N210, cannot be set at 52 MHz.
Inform the user that these devices can be used with the
compile time option of host based resampling.
