There are platforms that feature more than just APPS and Adreno SMMUs,
this implementation seems to assume there's only these two :/

I suppose the only way to solve this would be to introduce new compatibles
for each one of them.. Krzysztof, do you think that's reasonable? E.g.
MSM8996 has at least 5 instances, 8998 has at least 4 etc.
