Added enumeration for supported resampling algorithms. Coefficients needs to be programmed only for FIR mode. Bounded coefficient programmin API with required condition. Updated debug API to report resampler type and associated coefficients Signed-off-by: Rohit Consul <rohit.consul@xilinx.com> Acked-by: Srikanth Vemula <svemula@xilinx.com>
