ASoC: wcd9330: Optimize delay after micbias enable



Cold start input latency is higher than the target by
around 8msec during recording usecase. During device
path bring, after micbias getting enabled, there is
20msec sleep that is contributing for cold start input
latency. This change optimize the delay after micbias
enable to avoid latency.
