Are we aiming for new dts wto work with old kernels? It's nice if they
do, but I don't think it should be necessary. Old DTBs should definitely
work with a new kernel, though.
Personally I'd rather see one string (preferably the canonical one, but
the deprecated one is ok) than two strings when those strings are for
the exact same device.
