[PATCH] ASoC: rt5682: add delay time of workqueue to control next IRQ event

[<shumingf@xxxxxxxxxxx>]

From: Shuming Fan <shumingf@xxxxxxxxxxx>

This patch keeps the delay time (50 ms) for jack detection and zero delay time for the button press.
This patch improves the reaction of the button press.
