Wade Fife 81f150213f fpga: rfnoc: Add new FFT block 
This replaces the legacy RFNoC FFT block with a new one of the same
name that includes a superset of the original features. New features
include cyclic prefix insertion or removal and FFT sizes up to 64k.

// Description:
//
// Wrapper for the Xilinx FFT core, which allows you to configure the maximum
// FFT size using parameters.
//
// Parameters:
//
// MAX_FFT_SIZE_LOG2 : Log2 of maximum configurable FFT size. That is, the
// max supported FFT size will be 2**MAX_FFT_SIZE_LOG2.
