ANDROID: arm64: suspend: Restore the UAO state

Upstream commit d08544127d9f ("arm64: suspend: Reconfigure PSTATE
after resume from idle") when cherry-picked on LTS linux-4.4.y
removed UAO reset code because UAO is not supported in linux-4.4.y.

But common/android-4.4 has UAO support, added in Change-Id:
I1a6a74a1f33b92d54368bd99387b55cf62930903 ("UPSTREAM: arm64: kernel:
Add support for User Access Override").

This patch pick up the UAO specific changes of upstream commit
dropped in LTS cherry-pick.

Fixes: LTS commit 71710cd3 ("arm64: suspend: Reconfigure PSTATE after resume from idle")
