[PATCH] ARM: dts: sun[47]i: Fix display backend 1 output to TCON0 remote endpoint

[Chen-Yu Tsai]

There is a copy-paste error in the display pipeline device tree graph.
The remote endpoint of the display backend 1's output to TCON0 points
to the wrong endpoint. This will result in the driver incorrectly
parsing the relationship of the components.

Fixes: 0df4cf33a594 ("ARM: dts: sun4i: Add device nodes for display
		      pipelines")
Fixes: 5b92b29bed45 ("ARM: dts: sun7i: Add device nodes for display
		      pipelines")

This is a late fix for 4.15 that corrects an error in the newly
added display pipeline graph for the A10 and A20.

Applied (a few days ago).

This will be sent out in a pull request later.
