ASoC: SDCA: Add PDE verification reusable helper
Implement sdca_asoc_pde_ensure_ps() helper function to poll for PDE
power state transitions. Per SDCA specification, after writing
REQUESTED_PS, drivers must poll ACTUAL_PS until the target power state
is reached.
Changes include:
- Add sdca_asoc_pde_ensure_ps() to handle ACTUAL_PS polling with
support for device-specific delay tables or default intervals
- Export function via sdca_asoc.h for use by SDCA-compliant drivers
- Refactor entity_pde_event() in sdca_asoc.c to use the helper
