Up to now we have relied on the device type to identify a device tree
node creation function. Since we would like the vfio-platform device to
be instantiable with different compatible strings we introduce the
capability to specialize the node creation depending on actual
compatible value.
NodeCreationPair is renamed into BindingEntry. The struct is enhanced
with compat and match_fn() fields. We introduce a new matching function
adapted to the vfio-platform generic device.
Soon, the AMD XGBE can be instantiated with either manner, i.e.:
-device vfio-amd-xgbe,host=e0900000.xgmac
or using the new option line:
-device vfio-platform,host=e0900000.xgmac
