drm/sun4i: tcon: Generalize engine search algorithm Current "old" method to find engine worked pretty well for DE2. However, it doesn't work when TCON TOP is between mixer (engine) and TCON. TCON TOP has multiple input ports, but current engine search algorithm expects only one. This can be fixed by first looking for output port id and selecting matching input by subtracting 1 for the next round. This work even if there is only one input and output.
