ARM: EXYNOS: handle properly the return values

Browse source

The cpuidle_register_driver return value is not checked.
The init function returns always -EIO when cpuidle_register_device
fails but the error could be different.

This patch fixes that by checking the cpuidle_register_driver properly
and returning the correct value when cpuidle_register_device fails.
