The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some

When adding the R8A77970 EtherAVB device I failed to notice that it does
not have the usual "status" property disabling the described devices in
anticipation that the board device trees enable the devices according to
their needs. This causes the EtherAVB driver to successfully probe despite
e.g. the needed pins not having been configured -- luckily, "eth<n>" device
can't be opened anyway...
