The exceptions are the cheza plaftorms, which need to remain with PC idle states. So in order allow all the other platforms to switch, while cheza platforms to remain the same, replace the PC idle states with the OSI ones in the main SDM845 dtsi, and then override the inherited OSI states with PC ones, delete inherited psci cpus nodes, domain idle states and power domain properties.
