feat(fvp): fdts: add stdout-path to the Foundation FVPs

Add an `stdout-path' property into the `chosen' node of the Foundation
FVPs Devicetrees.

This gives a default console to the Linux kernel when "console=" is not
specified on the kernel command line, which is useful when booting with
U-Boot in UEFI for example.
