sched,powercap: Convert to sched_set_fifo*()

Peter Zijlstra · Peter Zijlstra · commit c3f47cf940ef · 2020-06-15T14:10:22.000+02:00
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.

Effectively no change.
