In order to test VSP+DU integration for Gen3 on Gen2, link the VSPD
instances to the DU and modify their features to match the Gen3 VSPD.
Remove the IOMMU properties for the DU as memory is now accessed through
the VSPD.

Why do you modify the feature properties? AFAIK the driver doesn't
look at them anyway.

It was a leftover, that's not needed indeed. It will go away when I'll rebase 
the series on top of your patch that removes those properties from 
r8a7790.dtsi.
