Transceiver52M: Allow startup delay for stream alignment

UHD requires a small amount of time to align multiple streams at
startup. Delay the startup by 100 ms relative to the queried device time
(actual delay inclusive of control latencies will be less).

The following error is only relevant to dual-channel UHD devices (e.g.
Fairwaves UmTRX and Ettus B210).

UHD Error:
    The receive packet handler failed to time-align packets.
    1002 received packets were processed by the handler.
    However, a timestamp match could not be determined.
