intel_idle: Initialize sysfs after cpuidle driver initialization

Reorder initialization calls to initialize the internal driver data before
sysfs:

Was:
intel_idle_sysfs_init();
intel_idle_cpuidle_driver_init();

Now:
intel_idle_cpuidle_driver_init();
intel_idle_sysfs_init();

Follow the general principle that drivers should initialize internal state
before registering external interfaces like sysfs, avoiding potential usage
before full initialization.
