Subject: [PATCH v3] drm/bridge: anx7625: Update audio status while
 detecting

Previously, the audio status was not updated during detection, leading
to a persistent audio despite hot plugging events. To resolve this
issue, update the audio status during detection.

Fixes: 566fef1226c1 ("drm/bridge: anx7625: add HDMI audio function")
