cpuidle: Remove unnecessary wrapper cpuidle_get_last_residency()
cpuidle_get_last_residency() is just a wrapper for retrieving
the last_residency member of struct cpuidle_device. It's also
weirdly the only wrapper function for accessing cpuidle_* struct
member (by my best guess is it could be a leftover from v2.x).
Anyhow, since the only two users (the ladder and menu governors)
can access dev->last_residency directly, and it's more intuitive to
do it that way, let's just get rid of the wrapper.
This patch tidies up CPU idle code a bit without functional changes.
