cpuidle: ladder governor - use macro instead of hardcoded value
use CPUIDLE_DRIVER_STATE_START, instead of hardcoded value 0. As, CPUIDLE_DRIVER_STATE_START can be 1/0 based on CONFIG_ARCH_HAS_CPU_RELAX is defined or not. Signed-off-by: Mohammad Merajul Islam Molla <meraj.enigma@gmail.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
