This change just make a little clean to make code more like drm core expect, move hdp detect code from bridge->enable(), and place them into connector->detect(). Note: Gustavo Padovan try to remove the controller and phy power on function in bind time at bellow commit: drm/exynos: do not start enabling DP at bind() phase But for now the connector status don't hardcode to connected, need to operate dp phy in .detect function, so we need to revert parts if Gustavo Padovan's changes, add phy poweron function in bind time.
