[PATCH v2 19/20] powerpc/pseries: Use pm_power_off rather than ppc_md.power_off

[Alexander Graf]

The generic power off callback is pm_power_off. Use that one rather than
the powerpc specific ppc_md.power_off.

Signed-off-by: Alexander Graf <agraf at suse.de>

v1 -> v2:

  - write pm_power_off in probe function
