Move the pm_power_off callback into one global place and also add an
function for conditionally calling it (when not NULL), in order to remove
code duplication in all individual archs.

Yes, but this doesn't seem to be ever called anyways. (in arch/alpha)
And, BTW, letting it point to machine_power_off() doesn't make much
sense, since it's the arch's machine_power_off() function, who're
calling pm_power_off().
Actually, we could remove pm_power_off completely from here, assuming
nobody would *build* any drivers that register themselves into
pm_power_off.
If you feel better with it, I could post a patch that just removes
pm_power_off from arch/alpha.
