cpuidle / sysfs: change function parameter
The function needs the cpuidle_device which is initially passed to the caller. The current code gets the struct device from the struct cpuidle_device, pass it the cpuidle_add_sysfs function. This function calls per_cpu(cpuidle_devices, cpu) to get the cpuidle_device. This patch pass the cpuidle_device instead and simplify the code.
