Lorenzo Pieralisi d2e5c871ed drivers: cpuidle: initialize big.LITTLE driver through DT 
With the introduction of DT based idle states, CPUidle drivers for ARM
can now initialize idle states data through properties in the device tree.

This patch adds code to the big.LITTLE CPUidle driver to dynamically
initialize idle states data through the updated device tree source file.
