Ok, found your v2 and tested it.

It solves the console problem on an imx6q-sabresd.

I have confirmed that v2 does not fix the case when stdout-path is not
passed in the devicetree.

While it is a good practice to describe stdout-path in dt, not all
devicetree files do this,
so 71066545b48e4 will cause regressions on several boards.
