powerpc/ppc4xx: Use generic accessor functions for gdsys FPGA
A set of accessor functions was added to be able to access not only memory mapped FPGA in a generic way. Thanks to Wolfgang Denk for getting this sorted properly. Signed-off-by: Dirk Eibach <dirk.eibach@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de>
