arm64: dts: mt8186: Change idle states names to reflect actual function 



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
