Is there some reason why we can't do this in the OMAP4 PM code?  At some 
point, I think it would be good to essentially disable all PM at boot, and 
then let the PM code specifically enable autoidle later in the boot 
process, etc.  The idea being that !CONFIG_PM would result in a chip 
programmed for lowest latency, etc.
