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.
