[PATCH v1 0/3] ASoC: qcom: add q6apm VMID support and qdsp6 GPR destination-domain routing

[Ajay Kumar Nandam]

This series adds two related pieces for Qualcomm audio paths that are not
always ADSP-targeted.

1. Add optional qcom,vmid support in q6apm-dai so fixed PCM DMA buffers can
   be shared with secure/non-HLOS VMIDs via SCM assignment when required.
2. Generalize qdsp6 AudioReach/APM/PRM packet destination-domain routing so
   packet allocation follows the active GPR device domain instead of assuming
   ADSP, while preserving ADSP fallback for legacy/default paths.

This is needed for platforms such as Shikra where audio may execute on mDSP
and buffer ownership must be explicitly shared across VMIDs.
