intel_idle: Fix a cast to pointer from integer of different size warning in intel_idle

commit 95e3ec11491d0cbce9fcdf1cc17a527c114c7dcf upstream.

Fix the following warning:

drivers/idle/intel_idle.c: In function 'intel_idle_cpuidle_devices_init':
drivers/idle/intel_idle.c:518:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

By making get_driver_data() return a long instead of an int.
