Feature request: add Krait C-States

[figue]

Hi! Can you consider to add Krait C-States for Qualcomm Snapdragon S4 Pro APQ8064 (Nexus 4)? In my case kernel parameters are:

/sys/module/pm_8x60/modes/cpu{0,1,2,3}/retention/{idle_enabled,suspend_enabled} /sys/module/pm_8x60/modes/cpu{0,1,2,3}/power_collapse/suspend_enabled /sys/module/pm_8x60/modes/cpu{0,1,2,3}/standalone_power_collapse/{idle_enabled,suspend_enabled} /sys/module/pm_8x60/modes/cpu{0,1,2,3}/wfi/idle_enabled

Values are simply 0 or 1 (disabled, enabled).
