I think this one should be dropped: Instead of modeling the DT based on what
is convenient for the current Linux driver implementation, we only want to
list devices in the dts that are physically present, and the "soc" is really
the sum of all the on-chip devices.

Better change the soc_device driver to bind directly to the "nuvoton,nuc970-gcr"
device.
