cpuidle/coupled: Remove cpuidle_device::safe_state_index
cpuidle_device::safe_state_index need to be initialized before
use, it should be the same as cpuidle_driver::safe_state_index.
We tackled this issue by removing the safe_state_index from the
cpuidle_device structure and use the one in the cpuidle_driver
structure instead.
