CHROMIUM: drm/bridge: anx7625: set downstream to normal on dp start

Since there are case where the display is not disconnected but
bridge_enable / bridge_disable would be called (for example, changing
resolution of external display), we need to set the downstream to normal
mode on anx7625_dp_start.

BUG=b:187887514
TEST=manually, change resolution and check there's output
