arm64: dts: fvp: Set stdout-path to serial0 in the chosen node

Add stdout-path to the fast models(FVP and Foundation) 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.
