Subject: [PATCH 5.0 20/95] ASoC: rt5682: Check JD status when system resume

[ Upstream commit 4834d7070c85a5fb69637265dbbb05d13043280c ]

The IRQ function may not work when system suspend.
We remove snd_soc_dapm_force_enable_pin function call to
make sure the bias off when idle and run into suspend/resume function.
