Subject: [PATCH 1/4] dt-bindings: remoteproc: qcom: adsp: document sm8550 adsp,
 cdsp & mpss compatible

This documents the compatible for the component used to boot the
aDSP, cDSP and MPSS on the SM8550 SoC.

The SM8550 boot process on SM8550 now requires a secondary "Devicetree"
firmware to be passed along the main Firmware, and the cDSP a new power
domain named "NSP".
