lk2nd: device: dts: Include model in all lk2nd device DTs

It looks like there are more and more SoCs that crash in some cases if the
model is missing in the DT. To avoid potential trouble caused by this,
include the model in all the lk2nd device DTs.

Set it to the DTB name, so it actually has some value (can use it to check
which DTB was selected).
