Pull the latest tree. I've just commented it out with a note.
I didn't rip it off so that people copying lite5200.c for their own 
board know how to activate
it if they need to ...
It can also be controlled from userspace /proc/sys/kernel/powersave-nap

You just need to be aware of the consequences ( like USB not working 
either ! ) if you want
to save power.
