drm: bridge: dw-hdmi: Fix the issue of EXTCON_DISP_HDMI state error

Browse Source 
First, echo off > sys/class/drm/card0-HDMI-A-1/status, the EXTCON_DISP_HDMI state is 0.
Then, echo detect > sys/class/drm/card0-HDMI-A-1/status, the EXTCON_DISP_HDMI state still is 0.
As a result, HDMI has no sound.
