m2k: Disable AD9963 core RX datapath again 

The RX datapath has a lot of things (IQ correction, DC filter, ...) that
take up a lot of space which are all not really needed in this project. So
disable the RX datapath.

It was previously enabled because the ad9963 core did not perform
sign-extension on the ADC data signal when the datapath was disabled. But
this has now been addressed.
