Subject: [PATCH v2 0/3] arm64: dts: qcom: Add ADSP, CDSP & MDSS support to SM8550 and MTP board

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.

Finally the firmwares file paths are added in the MTP board DT.

This patchset depends on:
- bindings changes at [1]
- base SM8550 DT at [2]
