Very early versions of the 1004K had an hardware issue that made index cache ops unsafe so they had to be avoided and hit ops be used instead. This may significantly slow down cache maintenance operations. Only very early FPGA versions of the 1004K were affected so let's get rid of the workaround which was only implemented for the DMA cache maintenance operations anyway.
