Revert "PowerHAL: add debug support for low power stats"

This reverts commit 1000b4e9fa.

Reason for revert: Broke build of partner-q-fs-release-generic-fs/mini_arm64-userdebug, which apparently has the device/google/wahoo project but not the hardware/google/pixel project.

Bug: 118339706

Change-Id: Ie6331a07b39267a8543fa0eacc0c7cd872d67119
