[PATCH 4/6] arm64: dts: mt8195: Change idle states names to reflect actual function

From: AngeloGioacchino Del Regno
Date: Thu Jan 26 2023 - 05:35:49 EST


The names of the idle states are misleading being this a single cluster
SoC, a cluster-off idle state is impossible!

After some research in ATF, it emerged that the cpu-off state is in
reality putting CPUs in retention state, while the cluster-off one
is turning off the CPUs.

Summarizing renaming:
- cpu-off -> cpu-retention
- cluster-off -> cpu-off
