Transceiver52M: Setup test case for second UmTRX channel

Feed the second channel with the same data buffer as channel one.
The two channel send maintains the same UHD interface, so we use
the same metadata for both channels. Hard code the second channel
RF frequency as an offset relative to first channel for now.
