Interesting question! I hadn't really thought about device tree. I actually
have very little understanding of how it works to be honest :-)
I'm happy to add loglevel support to device tree, I assume I'd add another
property under the chosen node, like chosen/stdout-loglevel.
Please do not add a new property there.
IMHO, the loglevel should be specified on the kernel command line,
and not be fixed using a DT property.
