[v7,2/7] arm: dts: qcom: Add SPM device bindings for 8974

Commit Message

Add SPM device bindings for QCOM 8974 based cpus. SPM is the sub-system
power manager and controls the logic around the cores (cpu and L2).

Each core has an instance of SPM and controls only that core. Each cpu
SPM is configured to support WFI and SPC (standalone-power collapse).

There is another reg property as part of the binding that should be
specified here.
