sc1200: remove stale Power Management code

* Nowadays core IDE code handles restoring of PIO and DMA modes
  (ide-io.c:ide_start_power_step() etc) so remove open-coded version
  from sc1200_resume().

  There should be no change in behavior because settings done by
  sc1200_resume() were always overridden by generic_ide_resume()
  and ide_{start,stop}_power_step().

* Bump driver version.
