[PATCH 2/3] arm64: dts: qcom: sm8550: add adsp, cdsp & mdss support nodes

From: Neil Armstrong
Date: Wed Nov 16 2022 - 05:55:04 EST

This adds support for the aDSP, cDSP and MPSS Subsystems found in
the SM8550 SoC.

The aDSP, cDSP and MPSS needs:
- smp2p support nodes to get event back from the subsystems
- remoteproc nodes with glink-edge subnodes providing all needed
resources to start and run the subsystems

In addition, the MPSS Subsystem needs a rmtfs_mem dedicated
memory zone.
