[PATCH v7 3/7] arm: dts: qcom: Add SPM device bindings for 8084

Lina Iyer [off-list ref] writes:

Add SPM device bindings for QCOM 8084 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).

Signed-off-by: Lina Iyer <redacted>

nit: This will need some more description, IMO.  The changelog talks
about SPM bindings, but all the stuff added refers to SAW.
