Switch from the flat PC idle states of sdm845 to OSI hierarchical idle
states. 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.

Changes since v1:
* fixed the commit message as suggested by Krzysztof
* dropped blank line sdm845 dtsi
* renamed sdm845 dtsi psci subnodes to power domain cpus and cluster
* fixed indentation for idle states in cheza dtsi
