[PATCH] arm64: dts: arm: Add stdout-path

Add stdout-path to the Arm devicetrees to specify the primary console.
This means that distributions can boot without the need for
platform-specific command line parameters i.e. they can use earlycon
with no parameters and no console argument is needed at all.
