[PATCH v2] arm64: dts: qcom: eliza: Add FastRPC support

[PATCH v2] arm64: dts: qcom: eliza: Add FastRPC support

[Abel Vesa]

Describe the FastRPC nodes for both ADSP and CDSP remoteprocs.

Signed-off-by: Abel Vesa <abel.vesa@oss.qualcomm.com>
---
Changes in v2:
- Rebase onto next-20260915.
- Drop the CDSP glink-edge description, as it was merged with the
  CDSP remoteproc support.
- Use the documented 0x1063-0x1066 secondary ADSP SID values.
- Drop the undocumented tertiary ADSP CB7 stream (0x1087).
- Link to v1: https://patch.msgid.link/20260721-dts-qcom-eliza-add-fastrpc-v1-1-cbea68d8e01b@oss.qualcomm.com

GPT tells me you should have a memory-region for the audioPD heap
(in case you copy-paste it, there are patches from ~today to do
s/reusable/no-map/ to prevent an unauthorized access after we map
the memory away through SCM)
