Change the xilinx device drivers and board code to include config.h instead of xparameters.h directly. config.h always includes the correct xparameters file. This change reduces the posibility of including the wrong file when adding a new xilinx board port Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
