Series arm64: dts: qcom: sm8650: switch to 4 interrupt cells to add PPI partitions for PMUs | expand

Commit Message

Neil Armstrong Feb. 28, 2025, 8:40 a.m. UTC 
The PMUs shares the same per-cpu (PPI) interrupt, so declare the proper
interrupt partition maps and use the 4th interrupt cell to pass the
partition phandle for each ARM PMU node.
