[RFC 3/3] PM / hibernate: Wire up system-power framework

[Thierry Reding]

From: Thierry Reding <treding@xxxxxxxxxx>

Use the system-power framework's equivalent to test for power off
capability instead of relying on the globally defined pm_power_off()
function pointer.

The system-power framework implements a fallback that relies on this
global function in case no system power chips have been registered.

Moving this to the system-power framework allows us to eventually
remove any traces of pm_power_off() once all handlers have moved over
to the new framework.
