sched,mmc: Convert to sched_set_fifo*()
Because SCHED_FIFO is a broken scheduler model (see previous patches) take away the priority field, the kernel can't possibly make an informed decision. In this case, use fifo_low, because it only cares about being above SCHED_NORMAL. Effectively no change in behaviour.
