TwinRX: Remove decimation from frontend
The decimation in the rx_frontend_gen3 was added to reduce the bandwidth
between the Radio and the DDC due to the limitation in bandwidth over
the crossbar for dynamically connected blocks. The default FPGA image
for the X300 now has a static connection between the Radio and DDC, so
this is no longer necessary.
This change allows the TwinRX receive channels to be time aligned with
channels from other daughterboards so they can be used in the same
streamer.
