[PATCH 1/2] ASoC: rt5682: optimize the power consumption

[shumingf at realtek.com]

From: Shuming Fan <shumingf at realtek.com>

Some settings should set to default value after the calibration.
This patch also disables the 25MHz and 1MHz clock power when the jack unplugged.
The JD is triggered by JDH, therefore this patch removes JDL setting.
