ASoC: wcd934x: Do not prevent the core entering power collapse

Do not prevent the core to enter into power collapse if it is
scheduled before ASoC probes the codec. Otherwise, digital core
will always be in ON state even after the device is booted up
and audio use cases are not running resulting in higher power
consumption.
