Since pnv_dt_xscom() is called from chip specific dt_populate() hooks,
it shouldn't have to guess the chip type in order to populate the
"compatible" property. Just pass the compat string and its size as
arguments.

Yeah. That is where I think a PnXscom model and class could be a little
cleaner. This is minor.
