Let me copy the note I added below the changelog for $subject patch,
as hopefully that should clarify the reason to why this is needed.
"- This patch is needed by the subsequent patch, but more importantly,
also by "[PATCH 10/18] drivers: firmware: psci: Add hierarchical
domain idle states converter"."
Kind regards
