Subject: usrp: support for multiple dsps in props and implemented in usrp1

usrp1 previously had 1 rx and 1 tx dsp with multiple freq params,
it now has N and M dsps each with one freq param.
This is more consistent with the multi-dsp model.
The hack here is to only apply stream commands and sample rate changes to dsp0.
