ASoC: WCD9310: Reduce the sleep time after lineout PA enable

Browse source 
- Speaker warm-up time is too long(over 100 ms) due to big delay
  (16*2ms for mono and 16*4ms for stereo)after lineout PA enabled.
- Measured by "adb shell dumpsys media.audio_flinger |grep measuredWarmup",
  speaker warm-up time is reduced to ~70-80ms
