ASoC: codecs: ES8326: Solve error interruption issue

[ Upstream commit 8a655cee6c9d4588570ad0cb099c5660f9a44a12 ]

We got an error report about headphone type detection and button detection.
We fixed the headphone type detection error by adjusting the debounce timer
configuration. And we fixed the button detection error by disabling the
button detection feature when the headphone are unplugged and enabling it
when headphone are plugged in.
