arm64: dts: mt8192: Change idle states names to reflect actual function

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

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

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