[PATCH v2] arm64: dts: qcom: talos: Add memory-region for audio PD

[PATCH v2] arm64: dts: qcom: talos: Add memory-region for audio PD

[Ekansh Gupta via B4 Relay]

From: Ekansh Gupta <ekansh.gupta@oss.qualcomm.com>

Reserve memory region for audio PD dynamic loading and remote heap
requirements. Add the required VMID list for memory ownership
transfers.

Signed-off-by: Ekansh Gupta <ekansh.gupta@oss.qualcomm.com>

Changes in v2:
- Fixed VMID list alignment.
- Link to v1: https://lore.kernel.org/r/20260418-talosaudio-v1-1-585ab22faaf4@oss.qualcomm.com

Is this for the QLI-QCS615 memory map, or LA-SM6150? I think it's
right for the latter, but I'm not super sure.

Plus, like we talked in another thread, I'm not sure this matters (dep
on whether UEFI reserves it?)

Yes, there is not entry in memory maps, this needs to be moved to
dynamic address range, like it is shared for kodiak, I'll fix it in next
spin.
