One of the state of CPUidle on Tegra can power gate the CPU and the vdd_cpu rail. But it depends on some configurations from DT and a common hook function for different Tegra SoCs to power gate the CPU rail. And these stuffs are initialized after common Tegra suspend init function. So we move the CPUidle init behind the suspend init function. And making the CPUidle driver more generic.
