[PATCH 01/20] powerpc: Support override of pm_power_off

[Alexander Graf]

The pm_power_off callback is what drivers are supposed to modify when they
implement power off support for the system.

Support a modified callback on powerpc. That way power off support code can
now either override ppc_md.power_off or pm_power_off.
