When dumping the VMA, include the parameters of the different GGTT views
so that we can distinguish them.

Type is %u, and maybe again compact like "rotated [[%ux%u, %u], [%ux%u,

Add default with MISSED_CASE and print the numerical representation?

Overall this approach solves the concerns with the map solution I
proposed nicely. :)
