Subject: [PATCH v3 0/2] Fixes for McASP and dmaengine_pcm

This series fixes two patches:

1. Fix the dmaengine API usage by calling dmaengine_synchronize() after
   dmaengine_terminate_async() when xrun events occur in application
2. Use the McASP AFIFO property from DT to refine the period size,
   instead of hardcoding minimum to 64 samples

Changes in v3:
- Use sync_stop() hook instead of a prepare() hook for the DMA channel
  synchronization
- Link to v2: https://lore.kernel.org/r/20240610-asoc_next-v2-0-b52aaf5d67c4@ti.com

Changes in v2:
- Fix compiler warning for prepare callback by marking it static
- Pass numevt directly to hw_rule_min_periodsize()
- Link to v1: https://lore.kernel.org/r/20240604-asoc_next-v1-0-e895c88e744d@ti.com
