Move the DP training and video enable from the hotplug handler into
a seperate function and call the same during dpms ON.
With existing code, DP HPD should be generated just few ms before
calling enable_irq in dp_poweron.
This patch removes that stringent time constraint.

Modify the driver to invoke callbacks for the next bridge
in the bridge chain.
Also, remove the drm_connector implementation from ptn3460,
since the same is implemented using panel_binder.

Since we don't use any image enhancement chips in exynos-drm,
we need to set FIMD BYPASS in DISP1BLK.
