[PATCH AUTOSEL 6.6 1/3] ASoC: rt722: add delay time to wait for the calibration procedure

[Sasha Levin <sashal@kernel.org>]

From: Shuming Fan <shumingf@realtek.com>

[ Upstream commit c9e3ebdc52ebe028f238c9df5162ae92483bedd5 ]

The calibration procedure needs some time to finish.
This patch adds the delay time to ensure the calibration procedure is completed correctly.
