Leave the bluetooth { } section out of it, but at least fix the bootargs bug and use stdout-path with the correct aliases. Postponing real fixes like this until next -rc1 is a stupid process.

backporting will be hard since these patches depend on changes that will only be available in 4.14-rc1. I don’t really know how invasive the patch that introduces uart0 for RPI 3 is.
However I am pretty sure that Loic can combine these two patches (and leaving the bluetooth { } section out) and send it with a proper annotation as fix.

Marcel
