Device-tree parsed multiple time in powernv cpuidle and powernv
hotplug code. 

First to identify supported flags, secondly, to identify deepest_state
and first deep state, Thirdly , during cpudidle init to find the available
idle states. Any change in device-tree format will lead to make changes in
these 3 places.

This series adds code to parse device tree once and save in global structure.

Akshay Adiga (3):
  powernv/cpuidle: Parse dt idle properties into global structure
  cpuidle/powernv: Change platform init to avoid reparsing dt
  powernv/cpuidle: Use parsed device tree values for cpuidle_init
