kset: convert /sys/power to use kset_create
Dynamically create the kset instead of declaring it statically. We also rename power_subsys to power_kset to catch all users of the variable and we properly export it so that people don't have to guess that it really is present in the system. The pseries code is wierd, why is it createing /sys/power if CONFIG_PM is disabled? Oh well, stupid big boxes ignoring config options...
