arm64: boot: dts: update rtsm aemv8 dts with PSCI and idle states

Browse Source 
This patch updates the RTSM dts file with PSCI bindings and nodes
describing the AEMv8 model idle states parameters.

PSCI function IDs compliancy with PSCI v0.2 is still under development
so this patch provides PSCI function IDs for demonstration purposes only.
