devicetrees may have a linux,stdout-path or stdout-path property
in the chosen node describing the console device. This adds a helper
function to match a device against this property and retrieve the options
so a driver can call add_preferred_console for a matching device.

NIce. Looks like the right behaviour, but is a little inefficient.
Since the stdout property doesn't change this code could be called
once right after the tree is unflattened and then cache the pointer to
the node anarguments. Can you add the code to of_alias_scan()?

do we assume that we can have only one stdout-path?

I think we could have more serial, framebuffer console
