It's unusual in that there's a child node ("da7219_aad") of the device node, to
encapsulate AAD specific information. The properties inside though are data only
and simple. Actually, as I read it this is exactly the kind of thing that the
'Hierarchical Data Extension UUID For _DSD' is for.

I believe there's the FWNODE_PDATA type as well so 3 things, although I assume
that this is to be used longer term instead of the old fashioned platform
data mechanism, for built-in properties. Right now though I don't see much
actual usage of this.
