When entering cluster-wide or system-wide power mode, Exynos cpu power management driver checks the next hrtimer events of cpu composing the power domain to prevent unnecessary attempts to enter the power mode. Since struct cpuidle_device has next_hrtimer, it can be solved by passing cpuidle device as a parameter of vh. In order to improve responsiveness, it is necessary to prevent entering the deep idle state in boosting scenario. So, vendor driver should be able to control the idle state. Due to above requirements, the parameters required for idle enter and exit different, so the vendor hook is separated into cpu_idle_enter and cpu_idle_exit.
