2118-2128: fix data rate spec
...
Quoted from the isolator datasheet: "Data rates up to 150 Mbps are supported."
Saying the maximum data rate is at least 150 Mbps is not very accurate.

4456: remove mention to cpld cfg on rf_sw
...
As communication to ALmazny mezzanine does not use bitbang anymore, there is very little value for routing LVDS signal.
Also, MUXOUT readout from ADF5356 has an easily understandable API available.
So there should not be any reasons to use EEM[4:8] for anything other than controlling RF switches.
