Of course, in the long term, these idlemode tweaking functions need to go 
through some kind of omap_bus/omap_device abstraction, since platform_data 
function pointers are going away with the DT conversion.  But since a 
decent omap_bus/omap_device is still a ways off, this is an important 
interim step.
