We hard code the metrics relevant for cpuidle states in the kernel today.
Instead pick them up from the device tree so that they remain relevant
and updated for the system that the kernel is running on.

Device tree properties should be documented, and these bindings are
getting very similar to the ones I have just completed for ARM,
I wonder whether we should take the generic bits out of ARM bindings (ie
exit_latency) and make those available to other architectures.

The firmware that emits those properties is already in the field, so it would
have been nice to use a generic binding but it's too late now.
