In device tree we never used nvidia,tegra132-ahub, but I guess it's
technically necessary, so I'll add that combination here, exactly as
described in the original bindings, and fix up the device tree to use
that instead.

They are there, further down below, though maybe somewhat hidden. The
per-SoC constraints define the exact items that need to go into each of
these. Though I guess I could expand a bit more and narrow down the
minItems and maxItems for each compatible.
