Device-tree parsed multiple time in powernv cpuidle and powernv hotplug code.
First to identify supported flags. Second time, to identify deepest_state and first deep state. Third time, during cpuidle init to find the available idle states. Any change in device-tree format will lead to make changes in these 3 places. Errors in device-tree can be handled in a better manner. This series adds code to parse device tree once and save in global structure. Changes from v1 : - folded first 2 patches into 1 - rename pm_ctrl_reg_* as psscr_* - added comment stating removal of pmicr parsing code - removed parsing code for pmicr - add member valid in pnv_idle_states_t to indicate if the psscr-mask/val are valid combination, - Change function description of pnv_parse_cpuidle_dt - Added error handling code.
