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.
