From: Jack Yu <jack.yu@xxxxxxxxxxx>
Fix clock stop prepare timeout issue (#2853).
The trigger of internal circuit which belong to
“SDCA preset stuffs” was not set correctly in previous driver,
which could block clock_stop_preparation state.
Add the correct register setting to fix it.
Fixes: 20d17057f0a8c ('ASoC: rt715-sdca: Add RT715 sdca vendor-specific driver')
