[PATCH] ASoC: rt766: trigger JD when system reboots

[<shumingf@realtek.com>]

From: Shuming Fan <shumingf@realtek.com>

The initial jack detection at boot time may be missed after a warm reboot
if the blind writes are not reloaded.

This patch triggers jack detection from the .set_jack callback to
ensure that the jack status is updated after a system reboot.
