As of Linux 3.15, the generic "stdout-path" property described by
ePAPR 1.1 is supported by the upstream kernel:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/of/base.c?id=676e1b2fcd9dbb47a59baac13d089621d22c68b8
ARM virt still sets the legacy linux,stdout-path.
Given that this step was added to ARM virt ~ 3 months after 3.15 was
released, could we simply replace it (patch below)?
Failing that, could we set both for now?

Subject: [RFC] hw/arm/virt: set stdout-path instead of linux,stdout-path
ePAPR 1.1 defines the stdout-path property, making the os-specific
linux,stdout-path property redundant. Change the DT setup for ARM virt
to use the generic property - supported by Linux since 3.15.
